homemade transfer switch

[James2029]

I'm thinking about doing a manual transfer switch. I have a 400 amp service with two 200 amp panels at the meter, and four sub panels one for the pool, the well, and two for the house. I want to make a generator outlet with a disconnect so when the disconnect is engaged the outlet can be used for the generator (when the power is out). I turn off both 200 amp main breakers and leave the well, and two sub panel breakers on so that will power up various circuits I leave on in emergency times like fridge, freezer, some lighting, and the well and septic system. I will be making joints at the sub panel main, and the well breaker then feeding into line side of the disconnect.

 

thank you

Hi James.

 

From your description of your supply I suspect that you may be the US (or at least on a US style electrical system). 

 

This forum is specifically aimed at electrical installations in Thailand which is 220V (230V in Bangkok). The biggest domestic supply generally available is 100A (22kW) although most of us get along on 45A supplies. A 400A service would supply a small factory and would certainly be 3-phase likely with a private transformer.

 

I'm going to lock this thread for now to avoid confusion, but please feel free to clarify where you are and what you actually have by PM and we can re-open if we can be of relevant assistance.

 

Of course I could be completely wrong (it has been known) in which case, again PM me and we can re-open.
