[Boatanchors] AC Meter Info left out

[WA5CAB at cs.com]

You must be running about four 304TL's.  Firing up a radar set?

Anyway, go to flex-core.com and click on solid core current transformers.  
Then on the datasheet for the one at the top.  They list a 75:5 with 1" ID.  
With photos.

But no, it does not run in parallel with the main transformer.  The two leads 
from the CT go to the meter.  One of the leads from the filament transformer 
secondary simply runs straight through the hole in the CT.  If you want to 
double the meter reading, simply loop the secondary lead back and through the 
hole again (which makes a 2-turn primary).  Etc.  I didn't see any prices, but 
the site does give phone numbers.  And I'm sure a lot of other companies make 
them.  If you live in a fair-size city, look for an industrial electrical supply 
house.  They probably stock CT's.
