What is a 10-30 outlet?


Quote from Youtube video: Nema 1030 outlets are commonly found in homes built prior to 1996. And are used for three-pronged dryers and level two ev charging. It has two terminals on an angle.

Can you plug anything into a 30 amp outlet?





So aside from not being standard, a 30 amperes circuit breaker circuit will not protect wiring and outlet with lower capacity. Having a specific 30 amp outlet and wire is the only way to use your 30 amp circuit breaker. However, you still shouldn’t use it as a common outlet in your house.

Is NEMA 10 30r grounded?

EV Charging Station Plug Warning: NEMA 10-30 has no Ground.

What are 30 amp outlets used for?

A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements.

What is the difference between 10 30P and 10 30R?

Older homes and dryers still have the 3-prong NEMA 10-30 plugs and receptacles. These NEMA 10-30P plugs will only work with the 30 Amp 240 Volt NEMA 10-30R outlet, as you know. If you purchase a new dryer or new construction, post-1996, then you will likely run into the 4-prong NEMA 14-30 plugs and receptacles.

How many volts is a 10-30 outlet?





NEMA 10-30 is an nongrounded 120/240V device (hot, hot, neutral), NEMA 6-50 is a grounded 240V device (hot, hot, ground). A 10-30 receptacle will be protected by a 30 ampere breaker, and supplied by wires only rated to carry 30 amperes of current.

What size wire can handle 30 amps?

10-gauge wire

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

How much can you run on 30 amps?

If you have a 30 amp system, you have to know how many watts your system is able to run. You measure this by multiplying amperage by voltage. This means that if you have a 30 amp system that uses 120 volts, then your maximum load is 30 x 120 which equals to 3600 watts.

How many volts is 30 amps?



120 volt

Another example would be determining the maximum wattage capacity for an RV with a 30 amp, 120 volt AC electrical system. The formula is 30 amps X 120 volts = 3,600 watts.

What uses 30 amps in a house?

water heaters



The 15-amp and 20-amp breakers often handle baseboard heaters, 30-amp serve water heaters and electric dryers, 40- and 50-amp are for electric ranges, and the 70-amp could serve a large air conditioner or a subpanel.

How many watts is 30 amps?

7,200 watts

30-amp 240-volt circuit: 30 amps x 240 volts = 7,200 watts.

Can I put a 20-amp outlet on a 30 amp circuit?

– Everything needs to be rated to match. You can’t use a 15A or 20A receptacle on a 30A breaker because if you had an overloaded device (not planned – malfunctioning) that pulled 30A, it would melt the receptacle but the breaker wouldn’t trip to stop it. Devices – lights, appliances, etc.

How many watts can a 30 amp fuse handle?



A 30-amp outlet supplies 3,600 watts (30 amps multiplied by 120 volts). Therefore, the breaker on that outlet could meet code and still trip anywhere between a total load of 2,880 watts (80 percent of 3,600 watts) and 4,320 watts (120 percent of 3,600 watts).

How many amps can a 30 amp breaker handle?

The safe maximum calculation is 80%. If breaker is rated 30 amp, then 30 x . 8 = 24 amp safe maximum.

How many outlets can you run off a 30 amp breaker?

The NEC states that you can only have 30-amp receptacles on a 30-amp circuit. If it’s a multi-outlet circuit, you can have a 20-amp breaker protecting the #10 conductors and use 15amp and 20amp receptacles on the circuit.

How far can you run 10 gauge wire for 30 amps?

How far can you run 10 gauge wire for 30 amps? 10-gauge wire is usually used for short 30 amp runs. If you plan on going over 150 feet, 8-gauge wire or thicker will be needed.

Is 30 amps enough for a house?



Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.

Do they make a 30 amp 120 volt receptacle?

30 Amp, 125 Volt, NEMA TT-30R, 2P, 3W, Flush Mount Receptacle, Straight Blade, Industrial Grade, Grounding, (For Recreational Vehicles), Side Wired, Steel Strap, Black *** Item is …

Can you replace a 30 amp breaker with a 20 amp breaker?

The answer is, “No, do not put a 30 Amp breaker in place of a 20 Amp breaker because the wiring is most likely’sized’ for the 20 Amp load and -may- overheat if a 30 Amp load is used with wiring sized for a 20 Amp load.”
