And by the way Brad, 15K, 30K, 60K diesel military gen sets...5 wires. Hots on L1, L2, L3, L4, and a nuetral. You will NOT use five. You WILL USE ONLY 3...L1, L2, and Nuetral. L1 to Nuetral...110, L2 to Nuetral...110, across L1 and L2...220. Actually, I should be saying 120/240 since thats what they are supposed to be.

My first exposure to three phase out in the field was because I was repair for microwave line of site, troposcatter, and satellite radio repair. There was this site where they had several comm vans hooked up to a 60K gen set, and someone hooked the five wire cables to the vans incorrectly across its coils. They got the color codes wrong at the coils, which meant they were wrong at the recepticals at the shelters. They had nuetral on a hot coil, hot on Nuetral, and at the equipment it got worse because someone tied ground to Nuetral on one van, which they didn't ground like they were supposed to, so when they fired it up everything that was ground was hot, and since it wasn't grounded and was separated from ground by the big rubber tires, the soldiers that walked up and grabbed the rails while standing in wet mud, became the fuses to ground and were getting knocked on their butts. Then someone did the same, but drove a ground rod like they should have, but when they hooked it up, shut down the 60k gen set because they were running a hot leg directly to ground. I got sent out because the entire site was down, like 20 or so communication vans off line and that was a big deal, and that site was the hub to all of the remote sites. That was my introduction to three phase...tracing cable connections through a huge load center back to the coils on a 60K gen set in the dark of night, me, a generator mechanic, a flashlite, a volt meter and some serious brass standing over our shoulders yelling at us in what turned out to be their operators mistakes.

Good luck.

Mark
