I haven't found any commercial AC current recorders that don't cost
more than you could ever save.

Mine is an old laptop connected to a Radio Shack 22-805 PC Link meter
with a clamp-on current probe. It won't measure wattage like a
120V-only KAW but it can record the highest current demand.

Per Jim Wilkins:

I never even knew such things existed.  

I could live without the clamp-on sensing... but a Kill-A-Watt
with a USB port and some PC software would appeal to my inner

The clamp-on measures current in hardwired 240V appliances such as my
water heater. It's a simple and safe way to record the On and Off

I use a cheap 12-year-old laptop without a battery because such
temporary card-table setups are rickety. A laptop won't tip over as
easily as a monitor, and it waste less power.

GE, SquareD, and Cutler/Hammer ALL make double Breaker Modules that
have TWO Breakers in a single Breaker Form Factor. Usually these are
15Amp Duals.... Just Say'en..... That would double your available
individual Breaker circuits, and they are ALL UL Approved, so No Code
