It starts with a heavy [[American Wire Gauge|gauge]] [[wire]] "drop" from a nearby [[public utility]] pole (or buried wires in some neighborhoods), which first connects to a [[electric meter|meter]] to measure electrical use for billing purposes.  This is in turn connected with heavy wire to a main service panel, where there will first be a main [[circuit breaker]].  The main breaker acts more as a switch than as a circuit protection device, and allows the de-energization of the wiring in the building so it can be worked on safely.
