Order No: Re: X.2778C Customer's No.: F.D. 61 Volt drop from battery to Switchbox on New Standard X.802 Glover wiring. Volts dropped on pos. wire with 10 Amps going to battery = .350 volt = .0350 w Volts dropped on neg. wire with 10 Amps going to battery = .418 volt = .0418 w (Including Ammeter shunt) Excluding Ammeter shunt + measuring volts from Ammeter terminal to battery V = .340 = .0340 w. (Total resistance = .0768 w.) Signed This Sheet must be filed on completion of the work. | ||
