[QUOTE="Rick Stansby, post: 1093, member: 312"] We are trying to figure out how to power our new amp racks that have 4@ Lab PLM20000Qs each. Each amp really needs a full 30A (or more), so an L21-30 won't do. We have considered using a pair of L21-30s to each rack, but there are a lot issues associated with that (no room for pass-thru on the rack-pack, custom rack-packs cost more, and we would have to run 2 cables to each amp rack). I am familiar with the 63A 3phase Ceeform connectors, but we don't see them very often in the US. If we switch to these connectors we will have to get the proper outlets added to at least one of our distros, also we will need new power cables to the amp racks. I mention the 120V current needs, but in fact we plan on running the amps at 208v once we get the power worked out. At 208v we need about 50A per leg, which is why we are looking at dual L21-30 or single 63A Ceeform. Is anyone here using ceeforms for amp rack power? Who made the rack-pack? Does anyone else have any other good suggestions to power these racks? Cam seems a little bit overboard, but not buy much. We currently use Cam, L21-30, L5-30 and edison exclusively. P.S. I like the crown V-rack power panels. [/QUOTE]
