From the breaker box on the service telephone pole, at the edge of my property, which then travels underground to my breaker box in my house where there is only one large line attached to the left side of the house breaker box. The other large line is not connected. It is too short at the breaker box on the telephone pole and my electrician has yet to hook it up. So, I am only getting power on one leg. This one leg has 168v. Will this less than optimal voltage keep the compressor on my outside unit from kicking on? Probably. [/quote] Ok, I understand better now. Yes, you probably don't have sufficient voltage to trigger the compressor. Sounds like you need that other leg from the power pole hooked up. Doesn't sound safe. [/quote] Thanks for the confirmation. I appreciate all the responses and it certainly puts my mind at ease. [/quote] You are probably not getting enough amps either without that second leg. Compressors generally pull most of their amps for startup. [/quote] Yes they do...10 gauge wire to my mini split 36000 btu MR Cool....But my 100 amp service runs it just fine....off a 40 amp breaker... My little electric box if topped off,with square QO ..With Tandems 20 amps all stuffed in it ... My father has a instant on water heater he hooked up with 2 40 amps going to the stand alone heater...on a 100 amp ...Works fine... But now since they got solar they upped him to 200 amp service ...so hes good.. But with my 100 amp service i have never had a problem running all my electric,My WELL,HEat Pump,Electric water heater ,My Sauna ,And all the other electric stuff i have running all the time...ITs been fine! I had my cousin come over an electrician and he looked at my panel and said you need a 200 amp service....this was 15 years ago...Its been fine so far no problems ...All wires in the house is all 12 Gauge since the house was built in the earlier ...they used all 12 gauge everywhere... Thats as much as i know,you should not have problems at all! [/quote] With all the other lights, fridge, water heater, etc. running at the same time was my point. Maybe I did not word my response correctly but if all of those things are running at the same time the new unit tries to power up, you could have an amp shortage. I don't know the conditions of other items at the time of testing. But sooner or later, most will be running at the same time. Expect possible issues until you get the second leg, which will provide another 100 amps, hooked up. [/quote]

Quick question:
I'm installing a mini-split system in my house with three heads. I know the outside unit takes 220v to operate and then from the outside unit a tthn wire is run to the indoor head unit. With the 30amp circuit breaker off, the outdoor dedicated shut off to the outside unit pulled, I still am getting current to the head unit. That is strange since there are no other wires running in the wall behind the head unit. (I wonder if there is a battery in the head unit).
Now here is my question. The outside unit and the inside unit do not operate when I have the fuse "on" and the outside shut off switch installed. I have a fuse panel installed that runs the outside unit but one side(pole) has not been installed. Hence, when testing the load from my service pole to my breaker box I am getting 168v to half of my panel and zero to the other half. With 168v coming into the panel and then going out to the compressor unit, is that enough to make the system run or is it too low with the voltage to make the system work?
It seems there is enough voltage to get to the head unit but not enough to make the system run.
I am going to contact my electrician and the mini-split company to figure this out, but in the mean time I just wanted a confirmation of my problem......not enough juice to make the components operate.
Thanks.
