The single contact should be rated for the full current. Usually, one set connects before the other, cooks, and then the cycle is repeated with the next set. Although I acknowledge that if the relay lasted even a short time longer with paralleling contacts, it's better than with only one set. No argumenet on this from an engineering standpoint John! The fact that it does work and the relay never fails is not explainable. There are relays that I modified over 15 years ago that are still cranking along. A better thing to do might be to add a snubber across the single set of contacts but since paralleling them works I've always just done that.

Of course it takes a 4kw lamp in one of those old LP's to equal a 2kw in a Super Lum-Ex! Perhaps thatas what he was thinking....?

But as Mark said from experience, I would go that route...  |  IP: Logged Dominic Espinosa Phenomenal Film Handler Posts: 1172 From: California, U.S.A. Registered: Jan 2004 posted 04-28-2005 04:15 AM                     Sorry guys, I'm a big dumbass. I'm really not even sure how I got to thinking it was a Strong. We don't have ANYTHING strong up in this booth! Anyway, the problem is still the same. Anybody got contact information for L.P. Associates? I gave Aaron a call today (and got a good ribbing for it) but we couldn't come up with anything new. Again, sorry for not having my facts straight.  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.
