Can you wire two 240 volt room air conditioners on one breaker?

This will depend upon the current draw of the ACs as well as the size of the circuit. My guess, based upon what 240V units tend to draw, is that you probably won't be able to, especially if the circuit is only 15 Amps. With a 20 Amp, you MIGHT be able to. You will have to check the nameplates on each unit to find what the current draw is and ADD THEM TOGETHER. And remember that AC units should be considered a continuous load. This is when a load may run for three hours or longer. Here, you must "derate " the circuit by 80%. So a 15 Amp circuit should only have a load of 12 Amps; while a 20 Amp should have a load of only 16 Amps. My best "guesstimate" is that they will need their own circuit.

How big of breaker do you use for 115 volt?
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
What size breaker should be used for 1500 watt bathroom exhaust fan heater?
20 amp breaker 12 gauge wire assuming its 120 volt
Will a 14-2 gage wire work for a 240 volt 15 amp breaker?
No. You will need a 14/3 with Ground.
Can one leg of a 240 volt circuit be capped and the circuit breaker changed to make an existing 240 volt outlet into a 120 volt outlet?
Yes, you can always have heavier wire than code requires.
How do I convert existing 3 wire 220 volt 20 amp breaker wire system to 110 volt from the box to the recepticle?
Assuming there is no neutral: 1) Turn off the breaker. 2) Disconnect 1 of the 2 hot wires from the breaker and connect it to the neutral bar (Recommend phase taping the wire white :) ) Remember which wire you used as the neutral, in a home you will most likely have a black and a red. I would keep the black hot, and phase tape the red wire white. If it's not long enough you can wire nut another white wire onto it to make it reach the neutral bar. 3) Leave the breaker OFF, at the receptacle, change it to a 120 volt receptacle. Take the wire you made the neutral, and connect it to the white screw on the 120 v receptacle, and take the black to the hot. Ground to the ground screw. Make sure you phase tape the red wire at the receptacle white as well. 4) turn the breaker on 5) test the receptacle with a meter or receptacle testing device for correct wiring.

What is the Largest amperage single phase 120 volt breaker made?
6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
What size breaker should be used for 1500 watt bathroom exhaust fan heater?
20 amp breaker 12 gauge wire assuming its 120 volt
How do you wire a 277 to 120 volt transformer?
The voltage 277 volts is a three phase line to neutral voltage of a 480 volt system. What is needed for the protection of the transformer is a two pole breaker from the 480 volt CDP (Central Distribution Panel). The breaker will be sized to the KVA of the transformer. The wire will be sized to the breaker plus 25%. The electrical code requires that on motor and transformer feeders, they be sized to 125% of the total current capacity of the equipment.
Will a 14-2 gage wire work for a 240 volt 15 amp breaker?
No. You will need a 14/3 with Ground.
Can one leg of a 240 volt circuit be capped and the circuit breaker changed to make an existing 240 volt outlet into a 120 volt outlet?
Yes, you can always have heavier wire than code requires.
Can you use 60 amp breaker for 110 V at 110 ft and what wire is best?
A breaker is based on wire size, as the breaker protects the wire and not the load. This is a voltage drop question. A #3 copper conductor will limit the voltage drop to 3% or less when supplying 60 amps for 110 feet on a 110 volt system.
How do you install a 2 pole CB 220 volt using AWG eight two wire to fuse box?
If it's a 220 volt circuit without a neutral bring wire into panel, put ground wire on ground bar, put load wires onto breaker.
How do I convert existing 3 wire 220 volt 20 amp breaker wire system to 110 volt from the box to the recepticle?

How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
What size wire and breaker is needed via 20ft length for a Westonhouse 1500w floodlight?
If it is a 110 volt light it can safely run on a 20 amp circuit with AWG # 12 wire.
What size wire for 75 feet of wire for a 30 amp 220 volt oven?
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
