What else can I help you with?
240v nema6-50r outlet wired with 6 gauge wire and 50 amp breaker you need to run a heater with a nema 6-30p can you simply put a 30 amp receptical in place of the 50 amp receptical?
Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.
Where would a 100 amp breaker be used?
In a residential application it would most likely be used as the breaker for the entire main electric panel or a subpanel feed.
Can you use a 2 pole 60 amp breaker to feed one circuit?
No, you cannot use one in place of the other.
How do you add a 240 volt receptacle to 100 amp supply?
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
Who many amps are needed to feed a 600 v to 480 v 3 phase 70 KVA transformer?
The equation for amperage when the kilowatts are known is Amps = kVA x 1000/1.73 x Volts.The electrical code states that a feeder for a transformer has to be rated at 125% for the primary and secondary load amperages.The amperage on the primary needed to supply a 70 KVA three phase transformer to its full capacity at 600 will be 68 amps. 68 x 125% = 85 amps. A #4 copper conductor with an insulation factor of 90 degrees C is rated at 95 amps.The amperage on the secondary needed to supply a 70 KVA three phase transformer to its full capacity at 480 will be 84 amps. 84 x 125% = 105 amps. A # 3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
Can you use a 40 amp breaker to feed a sub panel?
Yes, you can use a 40 amp breaker to feed a sub panel. The wire from the 40 amp breaker must be #8 or larger. If you intend to use the full 40 amps a larger conductor must be used. Conductors can only be loaded to 80% capacity in continuous load conditions. A #8 wire is rated at 45 amps x 80% = 36 amps. The suggested size would be a #6 rated at 65 amps x 80% = 52 amps.
Why did the breaker trip when you unscrewed a burnt out bulb?
This is a condition that should not happen under normal conditions. In North America the smallest home breaker is 15 amps. If a fault current is higher that the breaker setting the breaker will trip.The only way the breaker could have tripped is, if when screwing the bulb out, the feed wires feeding the light socket turned and shorted out against each other.Turn the power feed off and thoroughly check the feed wires. Make sure that the insulation is good all the way to the terminal points.As a side note, if the circuit that the fixture is connected to is fully loaded to say 13 amps it would only take an additional 2 amps to trip the breaker. If the bulb flashed when you started turning the bulb out, this is most likely what happened.

Is 60 amp breaker good for 225 stick welder?
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
Size of breaker for 5.4 kilowatt stove?
The sizing of a breaker is based on the amperage that the device draws. To obtain the amperage from kilowatts a voltage must be stated. Amps = Watts/Volts. The following values are based on the stove using a supply voltage of 240 volts. Amps = 5400/240 = 22.5 amps. The breaker required for this stove will have a 30 amp rating. The feeder supplying the voltage to the stove will be a #10 AWG.
Which terminal on a 15 amp household breaker does the hot wire feed into and which one does it come out?
On a 15 amp household breaker there is no terminal on the in feed of the breaker. The breaker either plugs into the distribution panel's bus bar or it bolts to the distribution's bus bars. The feed conductor connects to the load side of the breaker at its terminal lug.
How many amps will 10-2 wire carry at 100 feet?
A #16 copper conductor is not a wiring size that is used in homes. This is because the smallest breaker for residential use is rated for 15 amps. A #16 copper conductor is only rated at 13 amps. For a load of 13 amps over 100 feet a #12 copper would be required.
What size breaker is needed for a 220 v hot water heater?
A 220V hot water heater typically requires a double-pole breaker rated at 20-30 amps, depending on the specific power requirements of the water heater. Make sure to consult the manufacturer's specifications or a qualified electrician to determine the appropriate breaker size for your specific unit.
How many watts will a 30 amp two pole breaker handle?
A two pole breaker clips to adjacent buss in the breaker panel, supplies 240 volt power to equipnent like clothes dryers and air conditoning.The breakers have a mechanical common trip so if either pole exceeds its current rating both lines are opened shutting down the equipment.Each pole can carry up to its rated current of 30 amps.Hope this helps.
Can I feed 2 100 amp sub panels from my 200 Amp main service?
DO NOT FOLLOW THE INSTRUCTIONS BELOW!According to this logic, one could chain an infinite number or sub-panels off of a single one hundred amp feed. The second law of thermodynamics prevents this. An hundred amp service is not capable of powering another hundred amp service unless you are trying to move your panel and all of the circuits it feeds as well, without adding another hundred amp load. NEC (National Electrcial Code NFPA Book 72) states that certain loads can be derated but not to this extent.As far as the voltage drop is concerned, you need only worry about this with runs of about two hundred and twenty five feet or more for a 200 Amp Service running 2/0 2/0 4/0 URD direct burial aluminum.What you need is a new 200 Amp service to feed your original 100A panel and another hundred amps to feed your new load.for USA, Canada and countries running a 60 Hertz supply service.Yes you can as long as the feeder to the other 100 amp panel is equal to the ampacity of the breaker. In this case you would need to use a #3 wire rated at 90 degrees C if the distance to the other panel is under 50 feet. If the distance is longer that this a voltage drop calculation would have to be added to increase the wire size. My experience would lead me to believe that you could not install a breaker that was greater to or equal to the rating of the main breaker. To add a sub-panel, you will need to install a breaker that is half or lower than the main breaker.In your case, you have a 100A service; you will need to install a 50A or smaller breaker to service the sub panel.Consult an electrician if in doubt.If you have any doubts about an answer that you get, check the answerer's bio by clicking on their name to check their qualifications.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What is the breaker size for a 10 KVA electric heater?
The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.
