can anyone really dumb down the grounding of services and transformers. im wondering when i use which table, i remember one is for service and one is for equipment ground but can you dumb it down? when pulling wires to feed a new panel which table? when pulling wires to a meter socket or to feed a meter socket which panel? when do you change to the equipment table? after a breaker? but what if there is a main breaker? how do you size the primary and secondary ground for a transformer and the bonding jumper and the wire for building steel? i know its a very broad and extensive question but i could use some help understanding this. thanks alot
