Thanks Tim!

That's exactly what I'm looking for. In another reply by Bert, quote, "MOT
current limiting for consumer-grade ovens is designed to limit the fault
current during abnormal transient arcing conditions". unquote.

Always good to check here first!

Now I have a procedure to follow. Excellent!

The best way to measure a MOT is by feeding 120V or 240V (depending on MOT)
into the secondary. The primary should be around 5 to 6 Volts output. Then
you take 120V or measured mains voltage and divide by primary Volts.

120 V
_____  =  20:1 transformer or 2400 VAC

6 V


......then once your done that step use the mA current setting to measure
output current on the primary. This will tell you what sort of drawing rate
the transformer has.
