Welcome. My name is XXXXX XXXXX would be glad to assist.
Are you running residential cables or pipe and THHN wiring?
pvc and thhn.
Then with the THHN, #8 wire is good for the 50 amps you need, a #10 ground wire is all that is required for ground sizing.
Thanks. And for the initial line from the circuit to the fuse box, is #4 good?
What size breaker on the wire?
Is this conduit alos?
1 1/4 conduit for about 60 feet from the circuit to the 125 amp breaker box. The breaker on the jacuzzi wire is to be 50 amps. I will be installing it all.
I hope I answered your question properly.
Not sure, so let me give you the max on all the wiring------------#8 THHN is max at 55 amps, #6 THHN is max at 75 amps, #4 THHN is max at 95 amps (since they do not make a 95 amp breaker, you can up to a 100 amp)
Does that give the answer? Or is it something else?
If you want 125 amps worth, you need #2 THHN wire
I see. Almost exactly. So, is #4 good enough for this from the circuit to the fuse box? It is a 100 amp line with 2 hots and one common (right?). Does each "hot" carry a portion of the total amperage (100 amp/2 = 50 amps)? Once again we are reaching my knowledge limits. I need that 100 amps total, I will be wiring another fuse for my electric car.
You have it correct. The ground wire can be smaller, on 100 amp the ground wire can be #8 THHN
So, run your 3 wires for hots and the neutral, the #8 for ground
So in summary,Circuit to fuse box, #4 for hots and neutrals, #8 for ground will do.
That is correct, they will carry 100 amps
Ok, this was awesome. Thank you very much. I'm totally paying for this service. Thanks very much.Aloha,
You are very welcome. Glad to be of service. Have a great day
