460 volt step down transformer
STEP BY STEP - Stefan Hartmann
If you want run RV using fixed transformer 230V to 120V with high watt rated, no problem at all. A Variac (variable transformer) is to replace normal step down transformer. You don't have to buy normal transformer if you use a variac. The primary input will be 230V (house power). The secondary you can set between 0V to 270V.

208, 230 and 460 VAC operators use a step-down transformer to achieve 115 VAC operating voltage. B. Secondary Entrapment Prevention. The following two sections (1, 2) are for entrapment protection devices that are required per the U.L. 325 safety standard. One (or more) of these devices (1, 2), or combination thereof, may be required.

Consequently, it is generally used with unit-system installations where a single generator is connected through its individual primary grounded wye/secondary delta step-up transformer (or transformers) to the system. In a few cases, this type of grounding has been used when two or more generators are connected to one step-up transformer.

Medium voltages often supply distribution transformers which step the medium voltage down to low voltage to supply utilization equipment. ... the actual voltage limits for the 13 800 V system are 115 á 126 or 14 490 V maximum and 115 á 117 or 13 460 V minimum. If a distribution transformer with a ratio of 13 800 to 480 V is connected to the ...
