Mike,
I was wondering if you could give me some assistance with a wiring issue that we have come across . This in tells the marine industry. The problem that we are facing is the manufacture of a power cord recoiling unit refers to the NEC code to proper electrical installation. The boat manufacture installed this unit with 14 gauge wire. I had done the math and I calculated it needs to be 10 gauge wire. Here are the measurements a minim of 20 feet long is the distance that it needs to travel from breaker panel to D/C motor. The motor is 12 volts and under normal load it should require 7 to 9 amps according to the recoil manufacture. However on the motor specs it shows 13.1 amp. The problem is when I tighten up the pulley to grip the power cord better do to the cord slipping on the pulley the voltage drops down to 7 to 8 working volts and high amps. If I use a jumper wire 10 gauge from power supply to motor it reads 12 volts at motor and around 8 amps of draw. The boat manufacture claims that it is wired correctly yet I have a huge voltage drop and higher then normal current draw. The boat builder did have another company go to boat to evaluate the problem they to agreed wire is under gauge. Will you do your calculations to verify minim wire gauge required. Thank you for you time.
