a clue what is the source. (yes, we do no use dryer, little oven use,
etc)

I found that my expensive microwave pulls an insane amount of power
when it not in use. I've seen the same thing with TVs, too.

Easy to solve , pull an item each day while recoding consumption , often
the fridge as it ages or that telly

I discovered this when I hooked up each device through an AC ammeter. I
was *NOT* impressed!

The amount of current it's drawing is not a measure of the amount of
power it's consuming, because it doesn't tell you the phase relationship.

That is what I am doing. disappointed that the acre of glass (CRTTV) did
not draw oodles of juice so I could blame the high electricity bill on it.

The microwave draws nil as it has a mechanical switch.

Caveat, it draws 0.24 aps for 80% of the time and 4.5Amps for 10%.ten
second periods. We think it is breaking down.

The 4.5A will be when the magnetron is operating.

We think it is breaking down.

On older (non-inverter) microwaves, it's normal for them to cycle the
magnetron on & off to provide the lower power settings.

We were going to buy a new one,until I turned this unit around to see
what is should be and the label said 4.2A. Shrug, nothing wrong with it.
