The 240 volt, single phase models shall provide protection against excessive temperature through the use of an in-line heat/current sensor. The sensor shall be connected in series with, and attached to the motor windings 240 volt, single phase pumps requiring a sensor to be wired in series with the contactor coil shall not be acceptable.

This is a three-phase 240 V delta connected system, in which one winding of the transformer has a center tap which is connected to ground and used as the system neutral. This allows a single service to supply 120 V for lighting, 240 V single-phase for heating appliances, and 240 V three-phase for motor loads (such as air conditioning compressors).

Jun 17, 2002 · 120/208V, 3 phase, 4W- This is a good choice for a three phase system because you can balance 120 volt loads around the wye to equally load the generator. 208V single phase and 208V three phase loads can be used as well as 120V single phase loads. Motors must be rated 200 volt operation; 240 volt resistance heating equipment used on a 208V ...
