Hey I have questions about the largest motor… When comparing heat vs a/c… if heat is bigger and we omit the a/c then do we have to go to the next largest motor below that in appliances? OR even though we omitted the a/c… do we still use that to get our 25% of largest motor? Thanks!
No you do not use the AC in the 25% load calculation. You choose the next largest motor below that. Even Mike Holt teaches this. Read this: forums.mikeholt.com/threads/selecting-largest-motor.2440/ read the comment by "txinspect"
@@jarodvelectric7431 thank you! Second question (and I’ll probably ask you a lot more now that I have found you as a resource) when doing dwelling calculations (single or multi family) am I ever going to calculate heating or cooling as a CONTINUOUS LOAD and multiply them at 125%?

@markjohnsonkeys Yeah no prob! Ask away!
No, continuous load demand factors are only when you get into commercial load calculations.
Do you apply 83 percent rule after you have done standard or optional method? Or is that already applied in table 310.12, 100-400 amps.
