Basic algebra is must. adding, subtracting, dividing, multiply, fractions. some trig.
If you plan to be highly paid then should invest a little time and effort for algebra.
The more the pay the more you have to know and apply. At the end of the day, it is not much knowledge and much more pay.

Some examples of math on the jobsite are:

  • When caluclating how many wires run though a conduit
  • How many wire can be in an electrical box
  • The load on feed wires
  • The size of feeder
  • Voltage drop
  • Pending conduit
  • Number of lights and outlets on a circuit
  • The number of turns and angles of a conduit
the list goes on and on...
