I would trust speedy Pete on this. One thing he didn't say was if you know that an outlet will be for a high demand use such as a microwave or space heater giving it a dedicated circuit is a good idea.smiley said:how do i determine how many receptacles can be on a 15 or 20 amp branch circuit
While the 80% "guide line" might be a good idea, it is not in the code for a dwelling and is unenforcable. It is enforcable for commercial work. This "80% rule" is quite often misapplied, but causes no hazard when it is misapplied. Any intermittant load or group of intermittant loads (loads that run less than 3 hours) may be loaded to 100%.louis bugaj said:For 110 volts, 15 amps breaker max load is 1,655 watts .
For 20 amaps, breaker max load is 2,200 watts.
The design guide line is 80 % of max load. It is good to have no limit on the receptacles. But it is a good idea to know the average load on the circuit before adding a new receptacle. You don't want to add a receptacle for customer sump pump when the circuit is close to 80% load. Your customer might not think of you highly.
I'm always amazed at how the little local Nazi's think they know better than the 1000's of people in the code making panels who spend years revising the NEC every three years. I can really only advise as per the straight NEC. It's up to the installer to figure out how the locals might have perverted the NEC.jbfan said:What is enforceable is the AHJ. In my area 10 max per circuit!
Residentially, especially for lighting circuits, that is just flat out STUPID!!!jbfan said:, in the county that I live in you can not run 14 gauge on any new circuits, or on new construction.
Well Mdshunk, now EVERYBODY knows that good old voltamp definitely has had to many voltamps and that obviously makes him sooooo special !voltamp said:Where do these idiot come up with these questions?
For residential there is no limit.
Most stay at around 12 for 20 amp and 10 for 15 amp.
