120/240 Volt 3-Phase Delta High Leg | Electrician Talk
Jun 23, 2010There is less stress on a delta connected transformer from heavy motor starts than on a wye. And, of course, there is alot of single phase 240 V equipment as well as 240 V three phase stuff. And you need 120 V for general power and lighting, so the 120/240 V delta is pretty good for that. Of course, the 208 V high leg isn't used for anything

Jefferson Electric Buck-Boost Transformers
two-winding, single-phase transformer connected to boost a 208-volt supply to 240 volts. The autotrans - former is provided with a two-pole disconnect switch with both overcurrent devices (OC-1a and OC-1b) located on the supply side o f the auto- trans-former.

Household Wiring - Georgia State University
Household Wiring. The standard U.S. household wiring design has two 120 volt "hot" wires and a neutral which is at ground potential. The two 120 volt wires are obtained by grounding the centertap of the transformer supplying the house so that when one hot wire is swinging positive with respect to ground, the other is swinging negative.[PDF]

The third and last type of diagram is the installation diagram. This is a tool that is used primarily by the installing contractor. It normally shows only what the terminal board connections are, and very rarely will it include any internal wiring of the unit. Figure 3 is a typical installation diagram for a residential cooling system.
Aube Technologies RC840T-240 On/Off Switching Electric
This device makes no sense. It claims to control a 240 volt heater, but no device with only 3 wires can switch two 120 volt legs. You need a minimum of 4 wires (corresponding with line and load ends for both legs) in order to do that. So this device is clearly not a DPDT or a DPST relay.
