Compatibilities between awg wiring, breaker amp size, outlet amp size
Hi. Is there a resource out there, prefereably on the web, that outlines the compatibilities between awg wiring, the breaker amp size, outlet amp size, how many recepticles/outlets can be on x amp outlet, etc?
For example, it would be nice to see something that shows: you can use a 20 amp breaker with 12/2 wire on 15 amp or 20 amp outlets (if this is accurate, not sure); but you can't use 20 amp breaker with 14/2 wire.
Or another example... on a 15 amp circuit, with 14/2 wire you can use x outlets and x lights without overloading the circuit. Same for a 20 amp circuit.
Or, what size amp outlets can you use on different amp (15 or 20) cicuits?
It would be nice to be able to find all of this type of info without having to find/buy a code book that would probably be information overload. Appreciate your help.
