N. 208 Volt Primary Three Phase Isolation Transformers. TEMCo Three Phase Isolation Transformers are 50/60 Hz rated and come in a NEMA 3R enclosure for indoor use as well as outdoor protection against rain and sleet. Our transformers are built to last, guaranteed. That's why we back these with a decade long warranty. UL Listed, CSA Approved.We have a 3 phase 208V supply and need 480V for a motor. Would it make sense to do 208V delta to 480V delta? Or do 208V delta to 480V wye (and just not connect the neutral since it is not needed for a motor load).We have a 3 phase 208V supply and need 480V for a motor. Would it make sense to do 208V delta to 480V delta? Or do 208V delta to 480V wye (and just not connect the neutral since it is not needed for a motor load).In this tutorial, 277V and 480V, 1-phase and 3-phase circuits, we have used the NEC + general practice wiring color codes as follows. Brown = Hot 1 or Line 1. Orange = Hot 2 or Line 2. Yellow = Hot 3 or Line 3. White = Neutral Wire. Green or Green with Yellow stripes = Bare Conductor as Ground wire.

If there are 277 loads, then wire the H side exactly the same way you'd wire the X side if it were a 120/208Y. Reply. Save.

A Buck & Boost Transformer is an insulating transformer with either a 120 V x 240 V primary with a 12/24 V or 16/32 V secondary, or a 240 V x 480 V primary with a 24/48 V secondary. A Buck & Boost Transformer is also useful in applications where the primary and secondary are interconnected for use as an autotransformer.Jul 26, 2014 · Your 480v hot connects to H1. Your 480v white connects to H4. I'm not 100% on this part but from what I recall from school u need a jumper between H2 and H3. So they r in series. On the lv side 120v. Your 120v hot connects to X1. Your120v white connects to X4. Then jumper between x1-x3. And another jumper x4-x2. The job is a remediation trailer that has a few motors that operate at 240 3p and one or 2 120v circuits, my goal is to install a feed from the main panel 480v to a 100 amp disconnect I will install next to the transformer, then have a 100 amp panel on the secondary of the transformer the will subsequently feed the trailer panel (80)amps. ….
