This is Mike, Peg's husband. I have a question for any electricians on the board. I have a 200 Amp service with 30 breaker slots in it. Because I have a heat pump, and because everything in the house is electric, I have most of them taken up by big double-pole breakers. I'm putting new living space in my garage, and I decided to add a subpanel rather than use the half-wide breakers, as I heard they overheat. I have done house wiring before, but this is something I'm inexperienced with. So I have some questions.
I have looked at Lowe's and Home Depot, but it looks like the smallest 6-slot subpanel available is 100 Amp. Do I need that much capacity? And can my main panel handle it? Here is what I am trying to power with it.
1. Ceiling Fan and light and closet light in the new bedroom.
2. Ceiling light in my office
3. Ceiling light in the new laundry area.
4. Ceiling light in storage closet
5. Bedroom outlets (arc-faullt protected
6. Office outlets
7. Dedicated 20-amp outlet in bedroom for air conditioner
8. Dedicated bedroom outlet in office for air conditioner.(5000 btu units with heater - 15 amp circuit rated)
9. Smoke alarms.
Everything else already has breakers in the main panel.I am adding two breakers to the main panel - one for a freezer outlet and one GFI protected circuit that feeds an outlet in the laundry room and two others in a hallway area.
It seems like an awful lot.I know some of these can be on one circuit.Here, they make you put smoke alarms that are interlocked on their own circuit.
