They can provide proximity to circuit breakers, and they can reduce the amount of wiring required to add a new area to your power source. For the loads listed I00A would certainly be enough and not significantly oversized, but whether you should increase to a larger feeder is indeterminable due to future extension to outbuildings. Adding a new garage or shop will likely require the addition of a garage sub-panel. Many local codes make it illegal to install your own sub-panel, and some dont allow homeowners to do any of their own electrical work (source). For example, a 60-amp breaker may only be rated for 60 amps. You must calculate the unbalanced neutral current calculated on the subpanel. This can range from building shelves for the closet to building my Man Cave. Note that while the demand factor and the heater are both computed as per NEC Article 220 rules, the 3000VA for the tools circuit is an allowance (similar to a pair of Small Appliance Branch Circuits) for the heavy tools circuit due to the unavailability of details about the actual loads found there. Conductor - Choose the material used as a conductor in the wire. problems contact webmaster@doityourself.com. I seem to need too many circuits. WebBased on the estimated value, the next available and suitable size main switch breaker for the subpanel is 60A. It only takes a minute to sign up.
