I'm trying to build a pluggable power monitor to go in front of the power strips for what our British TV cousins call "derig" theatre setups -- folding tables and surface cabling in a theatre not set up for current-day equipment.
Alas, while it's easy to get this, with a 100A split-core CT:
and it's relatively easy to get this:
with only one hole in it for shortness, that's *still* a 10X current multiplying splitter, and the necessary 10 wraps of 14AWG make the posts so think the CT won't go around them... and larger CTs, 200 and 300A are too thick to fit the other way.
WHEREFORE:
Why the *hell* doesn't anyone manufacture a 1X CT sensor unit with a 5-15 plug on one side, and a 5-15 receptacle on the other, and some connector for the CT attachment, that's all a single damn unit, so I don't have to fight this battle?
The popularity of the P3 Kill-A-Watt tells me there's a market here, but if anyone's filling it, I can't find them...
