∙ 12y agoNot 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.
In a residential application it would most likely be used as the breaker for the entire main electric panel or a subpanel feed.
No, you cannot use one in place of the other.
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.
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.
It is not recommended to use a 40 amp breaker to feed a sub panel, as the breaker size should be based on the size of the wire and the load of the sub panel. It is important to follow the manufacturer's guidelines and local electrical codes when determining the appropriate breaker size for a sub panel.
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.

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.
To determine the amps of a breaker box, look at the main breaker or label inside the panel. The number on the main breaker indicates the maximum amperage that the breaker box can handle. Make sure not to exceed this amperage to prevent electrical hazards.
For a 5.4 kilowatt stove, you would typically need a 30 amp breaker. This is calculated by dividing the watts by the voltage (5,400 watts / 240 volts = 22.5 amps, which is then rounded up to the next standard breaker size of 30 amps to ensure safety).
For a 125 VDC battery feeding a 200 amp main breaker, you should use at least 2/0 AWG wire size to ensure proper current carrying capacity and safety precautions. Larger wire sizes could be used if the distance between the battery and breaker is substantial to minimize voltage drop.
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.
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.
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.
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.
Yes, you can feed two 100 amp sub panels from a 200 amp main service panel, as long as the total load does not exceed the capacity of the main panel. Make sure to properly size the conductors and breakers to match the amperage of the sub panels and adhere to all local electrical codes and regulations. It's always a good idea to consult with a licensed electrician for proper installation.
