Usually a general purpose house circuit is designed for 20 amps. Wire size chart and maximum amp ratings.
Step By Step Instructions For Wiring An Amplifier In Your Car
Ground wire for amp. Then run a single ground to the best source of ground the negative terminal on your cars battery. Current is measured in amperes or amps. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60c through 90c 140f through 194f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30c 86f. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. National electrical code nec 2014 edition table 250122. 122 gray solid cu uf b wg wire.
Ground wires are spliced together and attached with a pigtail to the box and receptacle. Pre amp grounds are soldered to the pot bus wire. You must supply the amps power and ground wiring an inline fuse a remote turn on wire rca cables and speaker wires.

The best way to ground your car stereo components is to run a 10 or 12 gauge wire from the amp and 12 gauge from all other components such as head unit and active crossovers to a central location. The grounding wire nut shown has a hole in its top that makes installing a pigtail easier. Bias supplies rectifiers or power tube cathode ground wires all go to the main ground point. The ground conductor size calculator will calculate the proper ground conductor size for grounding raceways and equipment based on ampere rating or setting of automatic overcurrent protection device in circuit ahead of equipment. One such method is a grounding clip that clamps the ground wire to the box. This is based on nec nfpa 70.
If your service panel does not have a separate grounding bar attach the ground wire to the neutral bar. Power and ground wires the power and ground wires need to be thick enough to accommodate the amps demand for electrical current or the amp wont operate properly or put out its rated power. Red or black by gs power. Step 4 locate grounding bar and attach the ground wire. Thread the ground wire through the knockout hole in the appropriate location usually on the bottom or the side on the service panel. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
All power transformer center taps get bolted down to the main ground point. 122 wire uf cable 3 conductors outdoor electrical wires direct burial outdoor electrical wires outdoor 82 gauge electrical wire 10 3 250 ft related products 250 ft.
