Electricity 101 for New Electricians: What You Should Know on Day One

Starting your journey as a new electrician? Whether you're fresh out of trade school or beginning an apprenticeship, here's a solid foundation to build on. These are the essentials every new electrician should know — and what will help you grow faster and safer in the field.

🧠 1. Know the Basics — Really Well

Before anything else, you must master:

  • Ohm’s Law (V = IR)
  • AC vs DC current
  • Circuits (series, parallel)
  • Voltage, current, resistance, and wattage
    Understanding the "why" behind your tools will make every job easier.

🧰 2. Respect Safety — Every Single Day

  • Always wear proper PPE (gloves, goggles, boots)
  • Know how to lockout/tagout power
  • Double-check for live wires even if the breaker is off
  • Don’t cut corners — bad shortcuts = big risks

🗂️ 3. Learn Local Codes & The NEC

  • Familiarize yourself with the National Electrical Code (NEC)
  • Your state or city may have specific add-ons
  • Knowing the code helps prevent costly redos — or failed inspections

📏 4. Get Comfortable With Measurements & Layouts

  • Know how to read blueprints
  • Measure for outlets, lighting, and conduit placement accurately
  • Learn how to lay out a circuit on paper and in real life

🛠️ 5. Tools You’ll Use Daily

  • Voltage tester / multimeter
  • Wire strippers & cutters
  • Fish tape, conduit benders
  • Screwdrivers, drill
  • Label maker (for panels and wires)

👷‍♀️ 6. Always Be Learning

  • Ask senior electricians questions
  • Watch what the inspector looks for
  • Take pride in neat work — it shows skill and care
  • Keep up with changes in codes and new tech (smart homes, EV chargers, solar)

💬 Final Thought:

Becoming a great electrician isn’t about knowing it all — it’s about being safe, sharp, and eager to grow. Every wire you pull and panel you open teaches you something. Stay humble, stay hungry, and stay safe.
