The former painting room was converted partly to a wheel-chair accessible washroom. The balance is going to be used as a spare part/expensive tool room.

The balance is going to be used as a spare part/expensive tool room. I would also like to rough-in provision for (but not installation of) a server rack. This requires provison of communications, electrical, and cooling. Also stored in the room will be an compressor, which will also need electrical and possibly cooling. | ||
The Compresser we purchased draws 13.5 amps (intermittant). This does not leave much room on the 15 amp circuit for other devices. When the bathroom was installed, a vent fan (CentriMaster 0.1 HP wall vent) was disconnected (orange wire). Those blue twist-on wire connectors in the upper right is where 240V split single phase power comes in (no other branches all the way to electrical sub-panel (by visual inspection of another junction box on east wall)). All of the outlets are powered by one side of that wire bundle. One set of lights in the room, plus the lights in the bathroom are on the same branch as the outlets. One set of lights is powered by the other branch. At 120Watts, the current draw is likely to be about 1.2 amps (assuming about 90% efficiency and 0.90 power factor). This leaves about 0.3 amps left over after the 13.5 amp compressor is added to the 15 amp circuit (for continuous draw, you would de-rate by 20%). | The Compresser we purchased draws 13.5 amps (intermittant).
