What else can I help you with?
Can you use 12-2 with ground to wire a 2000 watt forced air heater to a 240 volt 30 amp breaker?
(LIFE SAFETY WARNING!

Can a 3 wire load center be use in a 2-wire environment?
yes you can. but you will have less 220 v circuits. <<>> In North America if you only have a two wire supply it is usually 120 volts. To connect a three wire load center to this supply, a jumper wire is connected across the two lugs that would have taken the 240 volt input if you had that supply voltage. This is where your 120 volt supply is connected. The neutral of the 120 volt supply connects to the neutral buss bar. What this connection does is "hot" up both sides of the buss bar so that you will have 120 volts on each breaker outlet. By eliminating the jumper you would only have every other breaker slot energized.
Have 110volt refrigerator on a 30 amp breaker is that right?
Check the MFG for the amps it uses, if it is suppose to be on a regular 20amp line, then replace the breaker with a 20amp breaker. With the 30amp breaker,it will work, but if there is a surge, you could send too much power to the appliance and fry it. Most refrigerators, are just on a regular 120v household outlet. Besides a 30amp breaker must have 10ga wire, if the wire is 12ga,it can not be attached to a 30amp breaker.
Will it hurt to use a 40 amp breaker on a water heater the wire I was sold will not fit into the 30 amp on a sq. D circuit breaker?
In the United States, if the wire is #8 copper or larger (smaller number) it will work fine on a 40 amp breaker. If the wire is #10 copper, there is something wrong with the breaker if it does not fit. Pull the breaker out of the panel and look into where the wire terminates to see why the #10 wire won't fit.
Will a 100 amp breaker box work if there are 5 220 amp breakers and 7 110 breakers?
It will if the 100 amp distribution board is a 20 circuit board. Ten spaces for the 240 volt breakers and seven spaces for the 120 volt breakers. There are two types of 100 amp breaker boards, one rated at 100 percent and the other at 80 percent. Depending on what rating on the panel board you are using will govern the maximum amount of current that can be legally drawn from the board. This breaker board rating will also govern the size of the main breaker installed and the wire size to feed the board, either 100 amp wire or 80 amp wire. The second consideration is what are the connected loads to the breakers, with the total of seventeen breakers, the board can only supply as much amperage as the main breaker will allow.
What size breaker should be used with ceiling fans?
Use 15 amp breaker with 14 gage wire or 20 amp breaker with 12 gage wire. Either way will work just fine.
Can you wire a 347 volt ballast to a 120 volt fixture?
Yes, but it will not work.
Can you connect 110 volt circuit breaker to 220 volt circuit?
No, you cannot directly connect a 110-volt circuit breaker to a 220-volt circuit. Circuit breakers are designed for specific voltage ratings, and using a 110-volt breaker on a 220-volt circuit can lead to improper operation, potential equipment damage, or safety hazards. If you need to work with a 220-volt circuit, you should use a breaker rated for that voltage. Always follow electrical codes and consult a qualified electrician for such modifications.
How to split 220 volt into two 110 volt?
Answer for USA, Canada and countries running a 60 Hz supply service.Before an explanation of how to do this you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 120 volts.The existing two pole breaker in the distribution panel that is to be replaced should not have a larger rating than a 15 or 20 amps. The wire size from that breaker will be #14 or #12 respectively. The final results of this project will leave you with a 15 amp 120 volt receptacle and one spare 15 amp breaker in the distribution panel.That said, OK, any 240 volt outlet can be changed to 120 volt by removing the white wire from the 2 pole breaker and inserting it into the neutral bus bar. Remove the other wire (probably black) from the breaker. Remove the 2 pole breaker from the breaker panel. Install two single pole 15 amp breakers into the hole left by the 2 pole breaker. Leave both of these breakers turned off.Connect the black wire that came off of the 2 pole breaker on to one of the new single pole 15 amp breakers. Re install the cover to the electrical panel, this end is finished. At the old 240 volt receptacle, remove the existing device and install a new 120 volt receptacle.Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the 2 new breakers. Once you have the new 120 volt receptacle installed, identify on the electrical panel door what the breaker is used for. Leave the unused breaker in the off position. Turn the new 15 amp breaker on. Turn the main breaker back on. Test the new receptacle with a lamp to make sure every thing is OK.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Can you plug 230 volt 60 Hz 4.8 A pump into a household receptical with a GFI breaker?
No. A household receptacle is 120V. It will not work.
Can you run a 3200 watt oven on a 20 amp breaker?
a 220 volt, 3200 watt oven will draw under 15 amps, so yes a 2o amp breaker will work.
Is red or white neutral for electrical work?
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
What gauge wire for 240 volt 30 amp 55 ft?
10 gauge will work fine.
