Plug 6-20p
Janise Knollman
This NEMA plug is industrial/commercial grade and is made of highly durable polycarbonate thermoplastic with solid brass blades, making it virtually indestructible in most applications. The NEMA configuration and device rating are clearly marked on the front. Use in combination with a straight blade cord connector, such as Enerlites 66231-BK.
Is there a way to plug a 6-20p 208/220/250v plug into a 10-30r receptacle? I can't seem to find an adapter for this. I bought a 220v fahrenheat heater and want to be able to plug it into a range or dryer receptacle.
A 6-20 is a straight 240V grounding 20A device.A 10-30 is a 120/240V non-grounding 30A device, where the grounding function is provided via the neutral. This is only allowed in older range and dryer circuits, so any adapter would not be legal to use on any other circuit.
NEMA 10-30 is still in use. I just bought a 16A 240V EV charger and had an outlet installed by a licensed electrician. When you try to interchange with a live ground you may or may not get into trouble. If the power is coming from the main panel (not a sub-panel), ground and neutral buses are shorted together. But if someone tried to do this where the power came from a sub-panel, then there would be no path to earth grounding for the 6-20 load. So actually what you want to do is invalid since neutral cannot be grounded; see this page for more details.
I have a device that has a 6-20P plug (not the twist-lock L6-20P) that's current plugged into a 6-20R receptacle on the wall. This is in a business and I'm not sure if the power source is 208 three phase, or 240 single phase. All I know is that it's 6-20. I need to purchase a UPS to protect the device from brown-outs and surges.
I don't see any 230/240V APC models for the US, only 208V models with L6-20. If business's power source is 240 single/split phase, will the APC UPS's rated at 208V work? If this is the case then I will hire an electrician to make converter plugs to convert 6-20 to L6-20 so the UPS will plug into the receptacle and the device can plug into the UPS. Thanks

The risk comes from the wire going from the Receptical to your device, but ONLY if the device attempts to draw more than 20A for some reason. The wiring from the receptical to the breaker would be fine as it would all be rated at 30A.
I would consider it a fire hazard as someone could plug in multiple devices on the far side of the adapter, thus the SUM of the devices plugged into the adapter could exceed 20A and cause the adapter to become a improvised heating device and the 30A breaker would allow it.
So in this case, a jumper cord with a 20A Plug to 30A Receptacle is not typically a problem. This is often popular on some UPS and ePDU models we manufacture. We have provided similar cables in the past for our customers in the past successfully and confidently.
Most of the issues with 20A circuits feeding 30A breakers would be concerning fixed outlets. This is often a big problem, as once the original device is removed then a future device may be added overloading the circuit and presenting a risk to the site.
Whether at home or in the workplace, few things are as confusing as electric cords and the plugs, receptacles, and connectors that come with them. Meanwhile, you need the right plug and socket to get any electric device to work correctly and safely.
The NEMA nomenclature is the code of alphabets and numbers used to denote the configuration of a specific electric product. It applies to receptacles, represented by R, and plugs by P, ranging from 1-15 to 18-60.
Also, the first number indicates the voltage, while the second shows the amperage. Some products like NEMA L1-15R have L in front of the first voltage indicating the number to show whether the product is locking or non-locking. In this case, NEMA L1-15 is a locking 125V and 15A, two-prong receptacle.
Instead, the color-coding of a receptacle may be determined by a manufacturer or customer. In which case, colors like ivory, black, grey, or brown may help blend the cords and wiring of a building with the decor.
The NEMA chart and ratings were designed to enable electrical enclosures to operate safely while ensuring optimal functioning and compatibility of electrical products. Assuming you can understand the naming and what each number and letter means, you can know the best way to use your electrical products.
This applies to any place you go and use electrical products. But bear in mind that knowing isn't enough. It would be best to exercise the necessary precautions when dealing with electricity, especially when traveling abroad. When in doubt, ask questions and avoid making assumptions to prevent damage to life and properties.
