Re: anyone know what this pump's function is exactly
Jerome, Bill,
From the 2008 NEC (and this goes waaaayyy back). (underlining is mine)
- 110.13 Mounting and Cooling of Equipment.
- - (A) Mounting. Electrical equipment shall be firmly secured to the surface on which it is mounted. Wooden plugs driven into holes in masonry, concrete, plaster, or similar materials shall not be used.
Equipment. A general term, including material, fittings, devices, appliances, luminaires, apparatus, machinery, and the like used as a part of, or in connection with, an electrical installation.
Appliance. Utilization equipment, generally other than industrial, that is normally built in standardized sizes or types and is installed or connected as a unit to perform one or more functions such as clothes washing, air conditioning, food mixing, deep frying, and so forth.
An electric motor (such as an electric pump) is considered an "appliance".
