Just saw in the 2014 NEC where you can't feed anything off the garage outlets (outdoor outlet on the garage.) What is the logic behind this? Also, swimming pool wiring. I want to make sure I understood Mike's video clip I watched. If you are wiring a pool the panel that is feeding the pool circuit had to have an insulated ground? Does that mean if you have a main breaker panel and have bare copper to your rods and water that you have to run an insulated copper wire to your water pipes? Can you install a MLO panel off the main panel and feed it with either MC cable or conduit with all insulated conductors to meet this?
The logic in not feeding other outlets from the garage is, IMO, the NEC getting into design issues where they don't belong.:rant:
But having said that, it is for the electric car chargers and the current draw on them.
They don't want the garage overloaded because of this.
As for the pools you are misunderstanding what it's saying. They are talking about the EGC (equipment grounding conductor) not the GEC (grounding electrode conductor).
If it is a dwelling and the feed already exists it doesn't have to have an insulated EGC.
If you are running a new feed (outdoors) then an insulated EGC is required. It's always required to the equipment.
Nothing in the code pertaining to pools has anything to do with the GEC, ground rod, or anything with the dwelling grounding system.
