 o
future proof sizing of a subpanel

Posted by simanco (My Page) on

Hello,

We'll be replacing the upstairs fusebox subpanel and the wiring to it. Currently there are only three circuits, but the upstairs has no HVAC and will likely get it at some point in the future. Not to mention a possible need for new circuits at some point.

It is barely possible that we might want to put a small water heater upstairs - possible but unlikely. Other than that, and a future HVAC system, we are only serving 4 bedrooms and a bath.

I want to do this panel upgrade once and be done with it, but what should I go with?

Thanks,
Jim

Make a list of all things you might possibly want and determine how many circuits that requires. Then increase that number by 50%.

I wouldn't install anything less than 100a cable and 24 circuit panel. You don't have to feed it with 100a but you can in the future.
