I currently have a 20 amp double pole breaker supplying a multi-wire branch circuit for two 120v receptacles in a double gang box.
I'd like to remove the 120v receptacles and install a 240v receptacle.
Can I simply attach the two hots and the ground from the circuit? If so, what should I do with the neutral wire?
Best Answer
Cap the neutral off and you’re done.
However, since your breaker is 2-pole with common trip, you’re perfectly allowed to eat your cake and have it too. You can replace one side’s receptacle with either
That last option lets you make full use of the MWBC, and then, make full use of the 240V circuit... although, not both at once at max amperage. So an 8A/240V load will play nice with two 12A/120V loads, etc.
