low electrical volts

Are you using an extension cord?

I have my TT sitting next to the house with 30 amps supply line to it.

the guy who put in the service to the TT used two 30 amp Square D fuses.

I think this is your problem.

It is also suspicious he used 2. 30 amp service only needs one (120 volt) unless you have a 50 amp outlet.. I know when I had a house the outlet was bigger than the breaker.. but that was MY choice.

What was the actual reading?
I had one of those square, analog meters and it's read zone was overly sensitive to what's bad - I think it said 110 was too low. Also, it was very inaccurate compared to my calibrated Fluke. Ended up tossing it.
If it's over about 106VAC, it's fine.

This is all assuming you have a normal 30A service. If you really have two breakers on a 120V 30A service then your toast. Time the for electrician to pay up for repairs.

It is immediately suspicious of 2 FUSES (I think you mean breakers, but we work past that for now), because your TTs 30amp feed should only be 1 (One) 30amp breaker.

It sounds like you are not tuned to electrics, but you had best find someone that is right now. I am going to suggest that you find out what is going on.

If your electrician made the common (way too common) mistake, it could have already done a great deal of damage to anything connected. Many electricians, it seems, never read either the receptacle itself or the code about a TT30. The TT30 (two slanted blades and a round ground pin is a antique standard that got grandfather in and is still in use though it meets none of the modern standards. Many electricians assume that because the two blades are the same, it is a 230V connection. (Like a clothes dryer might be.)

Good luck, I hope I am wrong about the damage.
