Residential Wiring

lets end this so the CMP does not make it mandatory to have a circuit every 6' for "safety"

There is no Code maximum, but there is certainly best practice and experience.

I use very few 15 amp circuits, and when I do, it’s lighting only. I never put receptacles on 15A circuits.

I’ve done some places where each bedroom got its own 20A circuit, lights and receps combined, as space heaters were anticipated, but generally I like to keep them separate, so when the HO plugs in their space heater and electric blanket and a few toys all at once, and trips the breaker, they aren’t also in the dark, , but that’s not a Code requirement.

I try to use experience and common sense. I will put at least 2 circuits into garages, I never combine bathroom receptacles, each bathroom gets its own circuit, etc.

I ask what the budget is. if you're going to go cheap you get cheap. I hate waiting my time giving a Wonderfull designed home but they compare it to a cheap person and I waisted my time.
Hence why I gauge the client.
