Twin 120v breakout from 240v receptacle

In summary, the individual is attempting to create two 120v outlets from an unused 20 amp 240v outlet without access to the main breaker. They propose using a plug with two female leads, each supplying one of the 120v legs, with a common ground. However, this would not provide a proper neutral and the individual is unsure if this would be problematic for plugging in low-wattage items. They are seeking alternative solutions and have been advised to consult a licensed electrician for proper installation and inspection.

Hello, I live in the United States,
I have an unused 20 amp 240v outlet that has two hot legs of 120v and a ground. Id like to make use of this outlet to create two 120 v outlets. I cannot access the main breaker of this panel, and am wondering if I were to make a plug with two female leads supplying one of these 120v legs to each, would this work? I would common the ground for each female plug.
I realize that this would leave me without a proper neutral, and I don't want to bridge the two, rather create two plugs that could run two heaters, that are un polarized.
In short- female plug with pigtails using 1 hot leg and ground for the neutral, only plugging non polarized 2 prong, low-wattage things into them. Would this be problematic? What could i do to make use of this plug, besides converting my heater to 220v, which seems about as shady...

Welcome to the PF.

Please consult a licensed electrician. The work will generally need to be inspected by your city's building inspectors, and signed off after the electrician is done.
 

1. How can I convert a 240v receptacle to two 120v outlets?

To convert a 240v receptacle to two 120v outlets, you will need to install a 240v to 120v transformer. This will separate the 240v into two 120v outlets, allowing you to use two devices with lower voltage requirements.

2. Is it safe to install a twin 120v breakout from a 240v receptacle?

Yes, as long as the installation is done properly by a professional electrician and all safety precautions are followed. It is important to make sure you have the correct transformer and wiring for the conversion.

3. What are the benefits of using a twin 120v breakout from a 240v receptacle?

One of the main benefits is the ability to power two devices with lower voltage requirements from one outlet. This can save space and make it more convenient for devices that need to be close together. It can also be more cost-effective than installing two separate outlets.

4. Can I plug two high-voltage devices into the twin 120v outlets?

No, the twin 120v outlets are converted from a 240v receptacle and are only suitable for devices with lower voltage requirements. Plugging in high-voltage devices can cause damage to the outlets and potentially be a safety hazard.

5. Do I need to change the wiring in my home for a twin 120v breakout from a 240v receptacle?

It depends on the wiring and electrical system in your home. If your home is already equipped with a split-phase electrical system, then you may not need to change the wiring. However, if you are unsure, it is best to consult with a professional electrician to ensure the proper installation and safety of the outlets.
