split 20a receptacle
Hi, I want to install a new plug for my 2 treadmills. The treadmills are 120v, 20a. I was planning on running 12/3 bx to a 120v 20a receptacle and splitting it. Would be using a 2-pole 20a breaker as well. Is there anything wrong with this? Thanks

You will need to use a 20 amp duplex. A 15 amp duplex does not meet the code.
If this is in an unfinished basement you need GFI protection.

Well aware of that. I'm concerned of running both treadmills at the same time at full load

The neutral only carries the difference between the two hots. If both drew 16 amps then the load on the neutral would be 16-16=0. Even with only one running and again assuming 16 amps you would have 16-0=16 amps on the neutral.

Assuming both treadmills are on at the same time, why are the 2 load currents not returning to the power source via the path of least resistance, the wire connected to neutral?

A multi-wire branch circuit has the hots on opposite legs of the panel. The neutral is carrying thee current back to the panel. It is the difference of current between the hots, not the sum.
