Ac Amp Gauge Wiring. The most common gauges are 10 12 or 14. Connect the sensing coil wires to the meter.
Single-phase voltages are usually 115V or 120V while three-phase voltages are typically 208V 230V or 480V. A 20-amp receptacle circuit for plug-in appliances. If needed the sensing coil wires may be lengthened up to 50 feet 1524m using 16 AWG wire.
If the minimum circuit ampacity says 149 amps were good with 14-gauge copper wire.
Wire minimum with an insulation temperature rating of 220 F 105 C minimum from the battery terminal on the starter solenoid to the right terminal on the ammeter see wiring diagram. Amperage and Wire Gauge. Electrical current is measured in amps. Route the AC hot lead to be measured through the center of the sensing coil.
