Yes, they used the neutral for ground. Sure, the 10-30 doesn’t meet current codes for new construction – but if you already have one, using an adapter to plug in an appliance with a 6-20 plug is perfectly safe.
What is plug type 6 20P?
The NEMA 6-20P is a 3 Wire grounded plug featuring two line blades and a ground pin, rated up to 250V AC and 20A. The 6-20P has a horizontal and vertical blade to prevent attachment to lower ampere rated receptacles.
What is a NEMA 10/30 used for?
The NEMA 10-30 is an older style outlet that is rated for 30 amps and is commonly used for electric clothes dryers. Note: Not for RV use! This adapter is intended for electric car charging and therefore does not have a neutral connection.
Is NEMA 10 30r grounded?
EV Charging Station Plug Warning: NEMA 10-30 has no Ground.
What is a NEMA 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. If you plug a 50 ampere load, into a 30 ampere circuit.
What is the difference between NEMA 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 do you wire a NEMA 10-30 outlet?

What is a NEMA 6 50 outlet?
The NEMA 6-50 plug has a maximum amperage of 50 and is used for appliances that require a higher level of power, such as stoves and dryers. The difference between the NEMA 6-50 and the 14-50 is that the 6-50 has no neutral; it only has the two hots and the ground.
What does the first number in NEMA mean?
the voltage rating
The first number in a NEMA listing determines the voltage rating. A 5 represents a voltage rating of 125 VAC, while a 6 identifies a rating of 250 VAC. The rating given is the highest voltage allowed for use with the device by the standard.
How do you wire a 3 prong twist lock plug?

What is a NEMA 6 20 plug?
The NEMA 6-20P is a 3 Wire grounded plug featuring two blades and a ground pin, rated up to 250V AC and 20A. The 6-20P has a horizontal and vertical blade to prevent attachment to lower ampere rated receptacles. However, the 6-20R (receptacle) offers a “T” slot allowing connection of both a 6-20P and a 6-15P.
Are 4 prong to 3 prong dryer adapters Safe?
If you were to change from a four prong to a three prong and your dryer is designed to use 120 volts at some point, then that current will have to be returned on the ground leg. This is not acceptable by NEC code, nor is it safe.
How do you hook up a 4 prong dryer cord to a 3 prong dryer?
Quote from the video:
Quote from Youtube video: The back cover of the dryer or if it's hollow in the inside they would just fall to the floor. Now let's go ahead and insert the wire through the cable entry hole.
Can you use a 3-prong plug on a 4-prong stove?
All electric ranges will work with a three-prong or four-prong cord. Installing a cord is easy, but the wiring is slightly different for each type of cord. Switching from four prongs to three prongs or vice versa is just as easy, provided you know how to make the conversion.
How do I change a 3-prong dryer outlet to a 4-prong outlet?
If you want to replace your three-prong dryer outlet with a four-prong one, you have to run a ground wire back to the panel and connect it to the panel’s ground bus. An alternative would be to ground the outlet separately to a metal stake driven into the ground or possibly to a suitable metal water pipe.
How do you wire a 4 wire plug to a 3 wire?
Connect the ground wire of the 3-wire cable to the ground wire of the 4-wire cable. Connect the black wire of the 3-wire circuit to either the red or the black wire of the 4-wire circuit. The red and black wires are the”hot” wires. Either wire can be used to power a circuit.
Can you use a 3-wire on a 4 wire range?
In an existing installation (such as an older home built in the 1950s), it is considered Code-compliant for the kitchen range or the clothes dryer to be installed using a 3-wire cord and plug.
Can you connect neutral and ground together?
No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.
