At 29 amps of FLA, a voltage drop of even 1 volt will melt the
contacts in short order. I do not think that voltage drop will be a
good indicator.

Do the math, Mr. Algebra.com - any contact big enough to call itself a
motor starter will take 29 measly Watts all day long without melting
unless it's made of Wood's metal.


I think that 29 watts per contact (three poles makes 87 watts) will
quickly destroy the contactor.
