Slang Terms.I see problems with this transformer in more ways than 1. Most pieces of equipment that are 208v Single Phase are dual voltage 208/240v. If so, I'd be looking hard at a 480/ 120/240v single phase transformer that I could ground, keep the voltage stable, and, reduce my worries about it. JAP>Regardless of the specific purpose, understanding the wiring connections of a step-down transformer is essential for successful installation. To start, a step-down transformer 480V to 120V wiring diagram consists of two sets of terminals, labeled H1 and H2. The connection between these two is the high side of the transformer.The fact that the transformer is a wye is of no consequence. The voltage across any coil will not exceed 208, and the voltage from any point in any coil will not exceed 120 to ground. Think of a wye wound 3ø motor. The center of the wye is isolated from ground, just as it should be with a wye wound transformer.

Many people don’t realize that transformers are suitable to be supplied at the secondary voltage only if the transformer is marked for this application. For example, a transformer that’s marked as 480V primary, 208V …Step 1. Determine Transformer Current Ratings: Determine the primary and secondary current rating of the transformers: Step 2. Primary Protection [450.3]: The primary winding of transformers shall be protected against overcurrent in accordance with the percentages listed in Table 450.3 and all applicable notes.45 KVA Distribution Skid, 208Y/120V-480V 3PH, (6) 5-20R (1) CS8169, Male Camlock Receptacles Line-In

The ...Yes, in a typical industrial or commercial installation with a 480V service, you would use 480V delta to 120/208V wye step down transformer to provide for wall power and small 208V loads. Initially, you indicated that your transformer had a 480V/277V wye winding so that threw me off. A delta primary is preferable.Step 8- Change the shields on the transformer and any enclosures that hinder current flow. Switch on the feeder power circuit to apply the high voltage to the transformer and then turn on the ...

To find the secondary-to-primary transformer voltage ratio, divide the secondary voltage by the primary voltage. The secondary-to-primary transformer voltage ratio is 0.5 (240 ÷ 480 = 0.5). After multiplying the secondary conductor ampacity by the secondary-to-primary transformer voltage ratio, the result is 100 (200 × 0.5 = 100).

The 120/208v transformer is for 'normal' receptacles and small 3ph. loads. I'm assuming the OP has 120/208 service. Upping to 277v can be done with a transformer, but any energy savings that might be obtained will have a forever ROI. Changing the service to 480/277 is another option, but now you're adding a 480-120/208 transformer into the mix.Wiring Diagrams 7-12 - 7-13 Enclosure Figures 7-14 - 7-16 ...
