Default Requesting a second look at my wiring w/ a few questions.

This is my first real post on the forums, but have gather a ton of brewing knowledge from here. So first off, thank you everyone, HBT and PJ for the wiring diagrams.

I have already purchased and put together all my parts for an my ebrew system.

1 pot, maybe 2 eventually to get boil and mash
1 PID, 1 SSR, 1 contactor, 1 estop

I have everything wired up already, with a main switch for the PID, selector switch for the element (eventually going to go with 2 PIDs so I bought for expansion in the future) and a LED indicator light for the element being on.

I have read a bunch on here and know a bit about electrical circuits (not an expert mind you) and would like someone to take a look at my wiring.

I have a neutral going into the left side of the contactor that's T-off into the indicator light. Is this OK practice to T off, or run a separate line from the power block?

For line 1 into the PID power switch, and element switch, I used a line from the power block, to a fuse, then split out to each switch.

For the main lines, power block to SSR, contactor, element and such I used stranded AWG 10 THHN. For the PID power, LED contactor coil I ripped apart a 120v power strip and used those wires. So for anything providing power to the element I used 10 THHN, everything else I used the power strip wire. Will this be OK since I'm not running much into there? I also used this wire for the neutral. Ground is AWG 10 as well.

As of right now, nothing is soldered. Just using tape to keep things together until I confirm the wiring is complete.

I am using the auberins PID box. It has enough room for 1 element, but doesn't seem Ok for 2. Again, just using this for now until I move up to a more permanent solution.

I do have GFCI on this as well. I'm not stupid...

Does the power strip wire have a gauge marked on it?

Your diagram looks good. That should accomplish exactly what you are hoping.

My only recommendation would be to add fuses to protect the power strip wire. The size of the fuses would be based on the size of the wire.

It is a current limited circuit designed to trip the GFCI on his breaker.

Sounds good, a round about way of getting there.

I have fuses between the power block and the PID / switches. Should there be more? I have a 5 fuse strip with 3 available so I can add where needed. What do you recommend?
