Also, larger aluminum stranded building wire made with AA-8000 series alloy of aluminum is used for electrical services (e.g. service entrance conductors from the utility connection to the service breaker panel) and for larger branch circuits such as for sub-panels, ranges, clothes dryers and air-conditioning units.
Single-pole circuit breakers feed 120 V circuits from one of the 120 V buses within the panel, or two-pole circuit breakers feed 240-volt circuits from both buses. 120 V circuits are the most common, and used to power NEMA 1 and NEMA 5 outlets, and most residential and light commercial direct-wired lighting circuits.
Pole-mounted transformers may have lugs allowing direct mounting to a pole or may be mounted on cross-arms bolted to the pole. Aerial transformers, larger than around 75 kVA, may be mounted on a platform supported by one or more poles. [13] A three-phase service may use three identical transformers, one per phase.
Ground-based mounting supports include: Pole mounts, which are driven directly into the ground or embedded in concrete.
