Joliet 0 Posted April 17, 2015 I have 208 3 phase service, and I need to end up with 460-480 3 phase. Do I need a 208 delta to 460 wye transformer? It would need to handle 100 amps. Where would I find a quality transformer at a reasonable price? Thanks, Ken Share this post Link to post Share on other sites
bikeslut 1 Posted April 17, 2015 First; lick the outlet to find out if it's 9V or something higher than that...the 9V will tingle Share this post Link to post Share on other sites

Bagstr 287 Posted April 17, 2015 No. 1 - Hire a licensed electrician, that has Industrial experience. A truck slammer will hurt someone on this project. No. 2 - Failing that, http://www.sandiegoelectricalsupplies.com/ for a used transformer. No. 3 - A Wye trans has a nuetral / White wire; Delta just 3 phases and ground. Proper grounding is critical with transforers. No. 4 - I am guessing you need only the three phases without a Neutral for equipment. The Wye is center tapped for the neutral to get 120 vac. No. 5 460vac is delta, 480vac is wye with 120vac available. 208vac is wye with neutral. No. 6 Like I said, get an experience journeyman for this. All I know are signatory industrial outfits, Davies Electric, Fuller Electric, Chula Vista. I only work on the house and motorcycles, when I have one, these days.

SDlineman 0 Posted April 17, 2015 Bagstr's advice is pretty sound, with the only exception being 480v delta is around, but the only place I see it is for giant well pumps in groves and water districts. But it doesn't matter whether it's produced wye or delta as long as you only need the 3-phase power and it's wired properly. Share this post Link to post Share on other sites
