Great question Anelise, if you’re looking into becoming an electrician, you’ve chosen a very good career. Whether you choose to be an industrial or commercial electrician, this type of work will place you among the best-paid skilled workers in the workplace. With demand expected to grow in the following years, this makes it a very profitable industry. Even better, you don’t need an expensive degree to start working—and earning money—while you train as an apprentice. Below are some skills I believe you'll need to be successful as an electrician.
Ⓜ️ MATHEMATICAL SKILLS
Electricians spend a good amount of time measuring and calculating, so they need to have strong problem-solving and mathematical skills. This is important because incorrect calculations can lead to accidents, reduced efficiency, or expensive repairs. However, aspiring electricians don’t need to worry about complicated math problems, as electricians use basic math, algebra, and trigonometry when computing room dimensions, wiring, electrical loads, and conversions. Still, knowing advanced math wouldn’t hurt, as it can make understanding the concepts much easier.
🌐 UNDERSTAND BLUEPRINT
Electricians must be able to read blueprints and electrical plans so they can locate outlets, circuits, and panelboards. Being able to read blueprints will save time (and walls!) when doing renovations, repairs, or installations. Knowing where the wires are located will also save the electrician from accidentally breaking into a live wire and getting injured. It is also helpful when planning where to install certain appliances or fixtures, so as to reduce electrical interference and/or to prevent overloading the electrical system. Of course, being able to trace wires manually is equally important. But knowing how to read blueprints can save the client a lot of money—and for the electrician, their time and potentially, their life.
⏰ TIME MANAGEMENT
Electricians who make repairs in private residences often visit more than one worksite in a day. Clients expect electricians to keep appointments and arrive on time. Professionals must also allow for adequate time at each worksite to understand and resolve the electrical issue. Electricians who are good at estimating how long a job will take can avoid arriving late to appointments later in the day.
Electricians working at a construction site also need excellent time management skills. Construction projects work on a tight schedule. Every delay in the project costs the client time and money. Electricians must budget enough time to finish their projects without delaying the construction work as a whole. Additionally, electricians who work with a team must remain conscious of how their timeliness affects others. If one member of the team lags behind, parts of the project may not be able to move forward.
🗣️COMMUNICATION
Electricians often come into direct contact with their clients, especially workers who specialize in home repairs. These professionals must speak with clients on the phone to understand the issue and then interact with clients once they enter the home to solve the electrical problem. Electricians may also conduct follow-up calls with clients after completing the service. Even electricians who work in construction or service commercial buildings may interact with their clients. As such, electricians should develop excellent customer service skills. Customers expect electricians to act in a professional manner and solve problems in a timely fashion. Electricians should clearly communicate any problems and unexpected issues. Additionally, professionals in this field should maintain a positive disposition when dealing with customers. Electricians who keep their clients happy by being courteous and professional often retain customers. This can help electricians grow their business and create opportunities for more work in the future.
🚨 PROBLEM-SOLVING
Effective problem-solving involves diagnosing problems correctly and devising creative solutions. In some cases, electricians must think outside the box to resolve electrical issues at a worksite. These professionals must be able to think quickly and adapt to resolve problems for their clients. In many cases, electricians respond to issues at worksites they have never visited before. When called into a home or place of business, electricians must quickly familiarize themselves with the electrical system, identify the problem, and come up with a solution that will work in that particular situation.

Hey Anelise,
So becoming an electrician,⚡️🔌 It’s like being a wizard with wires! Here’s my take on what math and science skills are electrifyingly useful.
Basic Math Skills "Add 'em Up" Power!
Because, You’ll need to add, subtract, multiply, and divide like a pro—because calculations are part of the magic. Whether it's figuring out the total wattage or calculating how much wire you’ll need, it’s all about the numbers! Don’t worry, no one's asking for advanced calculus here—just solid number-crunching and fractions (those sneaky little guys pop up!). Surprise me, if they are!!!!
So. Algebra.
This one’s essential. Ever wondered why X is so mysterious? As an electrician, you’ll use algebra to solve for unknowns (like how much voltage you need or the resistance in a circuit). Think of it like being a detective in a mystery, only the "suspects" are voltage and current.
I heard an electrician say algebra, The X Marks the Spot Skill! You may figure what that means along the way.
There is Geometry "Shape It Up"
Its a skill!
Yep, you'll use it for things like figuring out the lengths of wires you'll need when running along walls, ceilings, or underground. Plus, when you're working with angles (like when you're installing outlets or wiring around corners), geometry will help you avoid any "sharp" mistakes.
Trigonometry The "Angle of the Dangle" Skill!
Okay, don’t roll your eyes! Trig isn't as scary as it sounds. You’ll use it when you’re dealing with angles and how to figure out the best way to run wires in different spaces. Need to figure out the angle of a conduit? Trigonometry is your friend. But please it isnt my friend I cant get my cone right!
Ohm’s Law
The Current Affair Skill! It’s like the golden rule of electricity! Understanding Ohm’s Law (V = IR—Voltage = Current x Resistance) will help you know how much power you need for each circuit. It’s a must-have for making sure you don’t accidentally overload a circuit (and set off alarms or, yikes, sparks!).
Electrical Theory
"Wires and Fire" Knowledge love calling it that! because this is your science foundation—understanding how electricity flows, what causes resistance, and how circuits work is crucial. You’ll need to know things like alternating current (AC) vs. direct current (DC), and the difference between series and parallel circuits (don’t worry, they’re not as complicated as they sound).
Safety Knowledge
The ZAP-Free Zone! I know i am too good at this!
Anyways,
Electricians get up close and personal with electrical hazards. Understanding proper grounding, insulation, and following OSHA (Occupational Safety and Health Administration) regulations will ensure that you're working safely. Because, let's be honest, no one wants to make a shocking mistake. ⚡
Now for a little paperwork, wonder why is paper involved!🤔🤓
For certification, you'll need to pass exams that test these skills, including:
National Electrical Code (NEC) knowledge: Rules and regulations that govern safe electrical practices.
Journeyman exams: They’ll test your knowledge of electrical theory, tools, codes, and more.
Apprenticeship: You’ll probably need to complete a certain number of hours under a licensed electrician to gain practical experience.
Final Tip: Always Keep a Screwdriver in Your Back Pocket (Just for Style!) Wait unless you need to fix my wires!
And my advice, because every electrician needs a trusty screwdriver ready for action, is:
Stay curious and keep learning. The world of electricity is always buzzing with new technology and techniques. So, stay sharp (and safe) while you work your electric rolling magic or sparking!
Good luck, Anelise—you’ve got the power to concour the world electricity-but con get electric shock! 💡✨

Energy Efficiency Design: Efficient design incorporates energy-saving features, such as LED lighting, variable frequency drives for motors, and energy-efficient appliances, all of which minimize energy consumption and reduce heat generation.
Compliance with Codes: Electrical designs must adhere to local electrical codes which ensure safety standards, such as proper grounding, circuit protection, and spatial clearance between electrical components and combustible materials.
5. Electrical Installation
The installation process involves bringing the electrical design to life by physically connecting components and wiring. The key steps include:
Planning and Preparation: Before installation, electricians review the electrical design, obtain necessary permits, and gather tools, materials, and equipment. They check that all materials meet code and safety standards.
Routing and Laying Conduits and Wires: Electricians lay out the conduit and wires according to the planned design, ensuring they’re routed through walls, ceilings, and floors while maintaining safe distances from other systems (e.g., plumbing and HVAC). Proper wire bending and conduit threading are essential for safety and accessibility.
Connecting Outlets, Switches, and Lights: Electricians install outlets, switches, and light fixtures based on the circuit design. They connect wires to the appropriate terminals, ensuring correct polarity (live, neutral, and ground) and ensuring that the grounding system is secure.
Panelboard Installation and Wiring: Panelboards (breaker boxes) are installed, and circuits are connected. Electricians carefully connect each breaker or fuse to the appropriate wires, ensuring the system is ready for load testing and operation.
Testing the System: Once installation is complete, electricians conduct tests to verify that the system is functioning properly. This includes checking for correct voltage levels, circuit continuity, grounding, and ensuring there are no short circuits or electrical faults.
Final Inspection and Compliance: After installation, electricians ensure that all work complies with local electrical codes. This often includes a final inspection by an electrical inspector who will verify the safety and compliance of the system.
By integrating these skills, electricians are able to design, install, and maintain electrical systems that are safe, reliable, and energy-efficient.
The requirements for becoming a certified electrician can vary by country, state, or region, but generally, the process involves a combination of education, work experience, and passing exams. Here’s an outline of the typical steps involved in becoming a certified electrician:
1. formal education. Training includes courses on: Electrical theory, Electrical codes, Safety practices, Blueprint reading, Circuitry and wiring systems, and Electrical troubleshooting.
Hands-on practice with electrical installations and maintenance.
2. Apprenticeship: Aspiring electricians typically complete an apprenticeship program to gain hands-on experience. This usually involves:
4 to 5 years of supervised on-the-job training. Working under the supervision of a licensed journeyman or master electrician. Completing between 1,000 to 2,000 hours of practical work per year. The practice includes installing and wiring electrical systems in residential, commercial, and industrial settings. Gaining experience with electrical circuits, troubleshooting, panel installation, conduit bending, and testing. Learning how to read blueprints and apply safety codes. After completing the apprenticeship, apprentices often have to document their hours and work experience to qualify for the certification exam.
3. Certification and Licensing Exam: After completing the required training and apprenticeship hours, candidates must pass a certification exam to become a licensed electrician. This exam generally includes both: written and practical exam.
Written Exam: Covers Electrical theory, National or regional electrical codes, Safety standards, Blueprint reading, Calculations (voltage, current, power, ampacity, etc.) and troubleshooting techniques.
Practical Exam: Some regions require a hands-on exam to demonstrate practical skills in installing and troubleshooting electrical systems.
4. Work Experience and Qualifications for Specific Certifications:
Journeyman Electrician: To become a journeyman electrician, candidates typically need to complete an apprenticeship and pass the licensing exam. Work experience (typically 4-5 years) under the supervision of a licensed master electrician is required to gain this level of certification.
Master Electrician: After becoming a journeyman, an electrician can continue to work towards becoming a master electrician.
This typically requires additional years of experience (usually 2 years as a journeyman), advanced knowledge, and more challenging exams.
A master electrician can work independently, run their own business, supervise other electricians, and even design electrical systems.
5. Continuing Education & Renewal: Ongoing Learning: Stay updated on codes, new tech, and safety standards.
License Renewal: Typically every 2-3 years, often requiring continued education hours.
6. Additional Certifications (Optional but Beneficial):
In some regions, electricians can pursue specialized certifications for certain areas of expertise:
Residential, Commercial, and Industrial Certifications: Certifying proficiency in different types of electrical systems.
Energy Efficiency or Solar Certifications: Specializing in renewable energy systems or energy-efficient installations.
Fire Alarm Systems and Security Systems: Specialized certifications for installing and maintaining fire alarm or security systems.

It really depends on what type of electrician you would like to become. I have done residential electrical work where I only needed a basic understanding of electrical theory and wiring/electrical codes (No math was really required). I have also done install jobs for HVAC that required some pretty basic algebra and required an understanding of refrigeration cycles. However, if you are interested in becoming an Electrical Engineer then that will require quite a lot of knowledge and training.
Below are my recommendations for basic math and science:
1) Physics
2) Electrical Theory
3) Algebra / Geometry / Trigonometry
4) Circuit Analysis / Schematic Comprehension
Here are some more advanced recommendations if you are interested in electrical engineering:
1) Electromagnetics
2) Semi-Conductors
3) Calculus
Getting certified as a master electrician -or- licensed as an engineer will require quite a bit more knowledge or study, but the learning doesn't end there. On the job training is major part of the electrical field. While electrical fundamentals don't change, the systems and locations are all very different depending on what the electrical system is used for. You could be working on a electrical system that powers a TV in your home, or a Refrigeration system at the local grocery store, or even an emergency pump at a nuclear power plant (I enjoy that last one). A Strong knowledge foundation will allow you to work in many different fields and get your foot in the door, but the effort and motivation that you bring to your job will drive you to success.
Once you figure out what specific job you want to do, it will be easier to understand the requirements are for that job. Hopefully this helped.
