You can run a wire from one of the outdoor outlets. 110, 115, and 120 volt circuits are pretty much interchangeable. An appliance rated for one of these will work fine on any of them. You may need to check the pump's amperage to be sure it isn't greater than the capacity of the circuit breaker.
You need to check the NEC concerning pool pumps. The pump must be GFCI protected. A licensed electrician should be consulted to ensure this pool system is done correctly and for the safety of people using the pool.
Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.
Yes, all wall receptacles are rated at 125 or 130 volts.
Volt....common household outlets are 115V
No, the circuit should not be energized when checking the resistance of a circuit.
It is not uncommon to find ratings on appliances of 110v,115v,120v,125v depending on where it was manufactured. Typically these ratings allow a tolerance of + or- 10%, meaning an appliance with a 110v rating may be plugged into a source that provides between 99v and 121v.
For residential service 110V, 115V, 117V, 120V, and 125V are all functionally the same. Electric companies have been slowly increasing the line voltage over the last 100 years to cope with increased loads. That is where these different voltages come from. The tolerance is generally +/-10%. That's +/- 11.5 volts in this case. So, a 115VAC appliance will run between 103.5 and 126.5VAC. The short answer is yes. 110V appliances can work with up to 130V without being burnt, additionally, 220V appliances can work with up to 240V without being burnt.
Absolutely not.
Depends of the current draw of the pump and if there is any other load on the circuit.
What's the reading at the service panel? What do regular 115V outlets read at? What kind of meter are you using? Chances are you have 480/277V 3 phase power to this building. Whoever wired the outlet used a 277V feed, possibly because 240V was not avaliable. You should call an electrician, repair of this problem may involve instalation of a transformer.
No. the plug configuration is different, just for that reason so that the two voltages can not be crossed over.
