Easy way to check were the problem is take a 6" piece of wire. Unhook the remote wire from your amp. Then hookup your 6" piece of wire to amp remote terminal then take other end and connect to the 12+ terminal. If amp powers up the its in the headunit. If amp does not powerup or goes into protect mode the amp is problem.
12 ga, 20 amp. 14 ga, 15 amp. 16 ga, 10 amp.
#12/2wground & a 20 amp breaker should be enough for lights,receptales.
14 gauge wire is for 15 amp circuits. At 220 volts that would be enough for 2.4 kw.At 120 volts it would need 12 gauge wire which is rated for 20 amps.
volts times amps equal watts. So 12 volts times ? amp equals 1.5 watts. The current is 1.5/12 amps, which is 1/8 amp.
Imperial cable 120/0.012" 60 amp Metric cable 120/0.30mm 55.5 amp 80/0.40mm 70 amp.
you will need wiring that is at least 10 amp rated wire or higher. If you really needed to ask you might want to call an electrician Electrician here, be the pump 120 volts or 240 volts a #14 wire will handle the situation. Longer runs of 75 feet you should go to a #12 wire to compensate for voltage drop. The pump should be on its own separate circuit with a 15 amp breaker. A two pole 15 amp breaker if the pump is 240 volts.
Yes, if you are using AWG # 10 wire. If you are using AWG # 12 then the answer is no you must use a 20 amp breaker. On AWG #14 wire you must use a 15 amp breaker.
12 Amps x 12 volts = 1200 watts 1200 watts / by 120 volts = 10 amps at 120 volts Answer is 10 amp hours
#12 wire will carry about 20 amp 20 X 480 volts = 9600 watts 20 X 120 volts = 2400 watts 4 times.
A #12 wire can carry 20 amps. Assuming the connected voltage is 120 volts the wattage will be Watts = Amps x Volts. W = 20 x 120 = 2400 watts. The circuit can legally be loaded to 80%. 2400 x 80% = 1920 watts. The maximum amount of loads that can be connected to a 20 amp #12 wire have to be added up individually but stay under 1920 watts.
Wrong question. I assume that this pertains to a car and not a house. All modern cars run on a 12-volt system. So what I think you meant to ask is "how many AMPS in 90 watts at 12 volts?". Watts divided by volts equals amps, so 90 watts divided by 12 volts equals 7.5 amps. If you are trying to wire in a car stereo amp, better go with a 10 amp fuse.
