Voltage drop is an important consideration in Traffic Signal and Roadway Lighting design. Failure to account for voltage drop can result in heating and inefficiency in operation, as well as problems in electronic equipment. There is no requirement in the NEC for a maximum voltage drop for Traffic...

Those unaware often use an AWG below the recommended rating because it is cheaper. They think it won’t make any difference. In the long run, getting a smaller one than what you should be getting will only cost you more. Professional electricians often recommend using a larger rating for yo...
I am doing conductor voltage drop calculations for a new subdivision. The secondary from my pad mount transformer is -probably- going to wind up at 350kcmil, but I need justification. I have 2 pedestals downstream from my xfmr. Each is feeding 2 single family dwellings with an estimated 10kW...
