What is receptaclein construction?

In NEC language, an outlet is any point on the wiring system where current is taken to supply equipment, which includes lighting outlets and hardwired connections, while a receptacle is the specific contact device you plug a cord into. In the field the words get used interchangeably, but the distinction matters in scope documents: an outlet count includes things that are not receptacles, so a quote per outlet and a quote per receptacle can describe different quantities.

NEC 210.8(B) drives GFCI protection in nonresidential occupancies for locations such as bathrooms, kitchens and areas with sinks, rooftops, and outdoor receptacles, and the list has expanded over recent code cycles. The takeoff consequence is that restrooms, break rooms, and roof equipment areas carry the GFCI premium, either as GFCI devices or as GFCI breakers in the panel. Check which approach the engineer specified, because protecting at the breaker moves the cost to the panelboard line.

A wall receptacle is a box, a device, and a plate in a stud wall. A flush floor box in a commercial slab needs coordination and placement before the pour or core drilling of an existing slab, a listed floor box body, fire rating considerations on elevated decks, and a flush finish cover rated for the flooring. Each step adds material and labor, which is why floor boxes and poke throughs are always their own line item, never blended with wall devices.
