18Non-powered typeThis type requires the field installation of a general-purpose125-v 15-A circuit powered from a source elsewhere in thebuilding. Observe national and local codes when selecting wiresize, fuse or breaker requirements and disconnect switch sizeand location. Route 125-v power supply conductors into thebottom of the utility box containing the duplex receptacle.Unit-powered typeA unit-mounted transformer is factory-installed to stepdownthe main power supply voltage to the unit to 115-v at the du-plex receptacle. This option also includes a manual switch withfuse, located in a utility box and mounted on a bracket behindthe convenience outlet; access is through the unit’s control boxaccess panel. See Fig. 26.The primary leads to the convenience outlet transformer arenot factory-connected. Selection of primary power source is acustomer option. If local codes permit, the transformer primaryleads can be connected at the line-side terminals on the unit-mounted non-fused disconnect switch; this will provide servicepower to the unit when the unit disconnect switch is open. Oth-er connection methods will result in the convenience outlet cir-cuit being de-energized when the unit disconnect switch isopen. See Fig. 28.Fig. 27 — Weatherproof Cover InstallationFig. 28 — Powered Convenience Outlet WiringUsing unit-mounted convenience outletsUnits with unit-mounted convenience outlet circuits will oftenrequire that two disconnects be opened to de-energize all pow-er to the unit.
