Re: Cabinet



Hi all!

  I sort of dis-reccommend using computer power cables...I'm using
one now to run my bank of NST's.  There's 6 12/30's in the bank,
and running a Jacob's ladder (really pretty!), the cord gets warm
in seconds, and hot in less than a minute.  I don't have any PFC
caps on it, but I was peaking around 15+ amps, and drawing around
5-6 steady.  PFC caps would reduce that figure a bit, but the cable
just isn't really up to handle it.  I'd recommend a good
construction-grade extension cable.  Home Depot has some thick (½"
thick) 25' cords that should work a lot better for that.  Most
computer power cords aren't made to handle more than a few amps
steady.  I like the idea of a locking box, but perhaps you should
locate it on the base of the TC, so nobody can just plug your
extension cord into any 'ole outlet.

    Just my $.02 :)  Keep it runnin man!

Caio!
                                                             Shad
