Where the maximum receptacle myth comes from.

I know where it comes from. Even though some of it is confused with the 180VA per strap in commercial establishments, most of it is people looking for a shortcut; an easy answer to a somewhat complex problem (except the NEC hands you the answer).

Early on when I was in electrical school, the class asked our teacher the same thing of how many receptacles go on a circuit in a dwelling unit. We begged him for an answer, other than the right one. He would have none of it, nothing about 'approximations' or 'averages'. Of course he was right as we suspected.

This myth should be buring in maybe a FAQ or sticky. And just point those folks to the right answer. I've seen some forums nearly rendered obsolete by people asking the same questions too often or talking about the same topics too much.

But there's too many myths out there to FAQ them all.

Wire nuts in a panel..... 100' run max of a raceway..... Pigtailing with 14s on a 20a circuit.... the list is endless.
 
Well are you going to tells us ?

OR

Just sit there and hold the facts back ? ;)

Welcome Aboard, ron_o... Enjoy the verbage!
 
there is no code rule on maximum number of receptacles in a dwelling unit. but if you do the service calculation you come up with a VA. using that VA number you can calculate how many 15a and 20a general receptacle circuits. then you can do more math to determine how many receptacles you can put on that circuit if you want but its not needed
