Re: Current Transformers

    If there is a 400 stamped on it is a 400:5 CT meaning if 400 amps
flows in the primary 5 will flow in the secondary.
Actually, it has "400:1" stamped on it.  I think that's a little better
but maybe not the best.  I was able to make a new scale for a 0-100 ma
AC ammeter to read 0-40 amps.  This should do for now.  

Our local electronics surplus has piles of the smaller ones
(100:5 and lower) for about five bucks a piece.
Care to do any "remote buying"?  What's their address?  Perhaps
I could talk them into mail order.
