480 to 208 transformer wiring
There are a couple of pieces of equipment/motors that are only available in 480/3. We are feeding them individually via 45kva 480/3 to 208/3 transformers wired in reverse. Delta Wye or in reality Wye Delta. The transformer manufacturer has confirmed that these transformers are rated to be used in this way.480V/460V/440V 240V/230V/220V 208V/200V 25V/24V/23V 120V/115V/110V High Voltage (HV) Install Supplied Jumpers Supply Lines Install Fuse (Primary Volts) Between Terminals Connect To Clips To 480 460 440 None 2, 6 Unfused 240 230 220 None 2, 4 Unfused 208 200 None 2, 3 Unfused 480 460 440 8-6 1, 5 2-7, 5-8 240 230 220 4-8 1, 5 2-7, 5-8

If the 480 side is a 4 wire Y then yes, you'll need to bond X0. If it's 3 wire ∆ then you'll need to ground of the phases or install a ground monitor.In Watt's Law, power (P) equals the output voltage (E) times the ampere capacity (I). Using this formula, P = E x I, and its direct derivatives, I = P / E and E = P / I, all transformer attributes can be calculated. For example, if the transformer's rating is 10 KVA and has a 240-volt output, it has a current capacity of 41.67 amperes (10,000 ...HOW TO SIZE A TRANSFORMER. Transformers are sized by determining the total load required (in amps). Transformer capacity is rated in KVA (kilo-volt-amperes). ... NOTE: If you need assistance with circuit protection devices such as fuses or breakers, or wire sizing, please consult a licensed electrical contractor or electrician in your area who ...The center-tap may be grounded at the transformer for safety reasons. 208 V is also available between the center tap and the third "high leg" of the delta connection. ... The three-wire, three-wattmeter connection has the advantages of indicating the power in each phase (not possible in the two-wattmeter connection) and phase to neutral ...
