it sounds a bit lite... i would think 6 gauge off hand. how are you hooking things up?

I think 10 awg should be fine for a 30 amp system. I decided to install a 30 amp gfci breaker in my main panel and run 10 awg wire to an outlet and then run a plug with that same 10 awg wire to the CP. Once inside the CP, I'm thinking I should be able to run slightly higher gauge wire on the circuits protected by the fuses. I only ask because it'd be easier to work with if that's the case. I guess I just need someone to confirm that I'm right our, explain where I'm wrong.

You are absolutely right. Fuse the pump and PID circuits & you can use much smaller wiring for them. You also might want to feed the contactor pick circuit from the 10A fuse feeding the pump outlets.

With that, you only need the #10 to feed power to the contactors and then to the elements.

Just a heads up:

I changed the wiring diagram so that the contactor pick circuits are now wired through the pump fuse (10A). Just refresh the drawing (page 5 post #41) and save the diagram for printing.

Looks good P-J. Thanks. I'll post a pic of all my new stuff in a big 'ole pile once it starts coming in. Then, I'll try to add some pictures of progress. This will be a slower build than some of the others I've seen, for 2 reasons:

1. Because I am slow by nature. LOL
2. Because I've got a little guy at home that requires my attention (and I don't mind giving it).

Now that is just plain awesome and right on the money. I applaud you in every way.

Thanks P-J. :-)

Silly fuse question:

I'm buying glass type fuses for the fuse holder I bought at radio shack. The 10 amp fuses I see are rated at 250V. I assumed I needed them rated at 120V. Is this incorrect?

Are the 10 amp 250V fuses what I need? Does the same apply to the 1.0 amp fuses?

The fuse voltage rateing does not matter in this case 120V or 250V - either one will work A-Ok.

Ok. Next question, which is based on the last diagram P-J added to the thread.

I'm going to use 14 awg wire after the fused parts. I know that the neutral wires should also be the same gauge or bigger based on what they're hooked to.

What gauge wire do I need to use for the neutral wires between the ssr, pid, pump outlets and back to the neutral bus?

I guys I'm confused because the hot line feeding the ssr is not fused and will be 10 awg. But from the pid back is all fused.

This might be a dumb question, but remember, I'm learning here.

#14 is ok for all of the neutral circuits.
