A Few Random Questions


The 125% is based on ampacity of the circuit, which is higher then the OCPD
This just came up in another thread
This same topic comes up it seems every month or every other month
The NEC has so many different parts that some seem to directly conflict each other
Until you find another section of code.....that refers to another section of code

I have seen the 1875w hair dryers mentioned in another thread
Seems like they shoot themselves in the foot as a lot of people with a 15a bath circuit will bring it back
Yeah....that's just under 80%
My pool pump, which can be 120v & plug in...is rated at 18.6a

Are you ignoring the rest of 210.23 ??
Re-read the very 1st paragraph
I'm not sure I get your point?


But from what I'm reading in all of 210.23, on some level, I think you and joseph were both right and everyone was getting tripped up on symantics without anyone fully qualifying what they were talking about.


For example, Dave, I agree with your claim that you can run a circuit at 100% of rated load. But the unexpressed caviout is that the load must NOT be a continuous load, and that load must be made up of more than one device.

On the other hand, joseph's claim of limiting your self to 80% of the circuit's rated capacity is correct when you are talking about a single device or a continuous load. (so it sounds like joseph was remebering something about an 80% rating, but just not recalling all the details).

OK, help me out here. I haven't seen this abreviation before, and when I google it, I get "obsessive-compulsive personality disorder", and "Oklahoma City Police Department".

NO NOT generally...only when the load is continous
Residential lighting is NOT considered a continous load under NEC
Every electric heater I have ever had installed has had a dedicated circuit
Plug ins are usually rated at 1500w or less = 83.3% of a 15a circuit
Do you think homeowners DO NOT plug these into a 15a circuit?
Do you think they run around & unplug everything else from a 20a circuit to make sure they do not exceed 80% ??
...so you dont leave your lights on for over 3 hours at a time??? how is that not continuous!!

ITS NOT CONTINOUS PER the NEC
It's quite obvious that you have not read the NEC
I suggest you read the NEC
