I am in the process of building my own home and will be wiring my breaker box tommorrow. The question(s) I have is the size breakers needed for certain circuits. I think I have it right but thought I would bounce my ideas off of ya'll since lots of people have good advice on here. Here goes dryer 30amp double pole. water well 2hp 30 amp 2 pole. septic aerator 30amp 1 pole. 5 ton AC 50 amp 2 pole. 3 ton AC 30 amp 2 pole. Double oven 50 amp 2 pole. Rv hook up 50 amp 2 pole. Hot tub electric outdoor 50 amp 2 pole. If these are correct please tell me and if they are incorrect please advise what would be appropriate. Thanks in advance.

 

you have 400Amp service?!?!

 

That is correct 400amp service

 

Everything looks good, Im not 100% on the AC's but they should have ratings on themselves which you probably already know.

 

Only the evaporator coils are in now but I will call my AC guy in the morning to confirm with him my ideas the 5 ton might be a 60amp but I'm not 100% on that

 

If you have 400 Amp service, everything else looks fine. you have a bit of wiggle room there for a few 15A single pole circuits.

 

You need to refer to the individual appliance ratings. Ensure you have installed the appropriate wire size. (I assume if you are wiring the distribution box the wiring is already in place)

 

Correct wiring is all in place and secure and proper wire size was used after much research

 

The various equipment/appliances should all list an ampacity rating for the wiring along with a max breaker rating. As long as the breakers you are planning to install are at least as big as the devices' ampacity ratings and do not exceed the max breaker ratings, you should be in good shape.

That must be some well to require a 2HP pump.

 

The well is 425' deep and I wanted a lot of water it will produce 18 GPM. A neighbor down the road says he has a 5 horse I have no idea what its GPM is. I talked to the guy who dug his well and he said it is big waste of money for a residential well, but that guy has the best of EVERYTHING (including a dodge)

 

A 400 amp service seems unusual for a home. Normally I see 200 amp services. Also, your spa needs to have a 50 amp, two pole, gfci breaker directly accessible to the spa users no closer than 5 and no further than 15 feet away. Also make sure you use 4 thhn conductors. 1-ground, 1-nuetral, 2-hots. You'll need the nuetral to run the 110v parts on it, and a nuetral to properly connect a gfci.

 

400 amp residential service means a BIG HOUSE....$$$$$$

 

Thanks for the all the advice I'm off to wire it up.

 

Good luck. I'm starting the same thing on my house....which from the sound of it will be about the size of your living room

 

If I'm not mistaken, the already installed wire size will determine the largest breaker that can be used for a given circuit, e.g. 10 AWG = 30 amp, 12 AWG = 20 amp, etc. Someone correct me if I'm wrong.
