Adding a 240v outlet to a dryer receptacle.

[spiralsmurf]

I got a new light that is 240v only there is 30a dryer receptacle in my room. I'm currently using it for my dryer, but, the dryer is already never used when the light is on so there would be no conflict for load. I need to run just a single 400w ballast, so for sure under 3a. Can I just add a 6-20R or 6-15R receptacle in a junction box and connect it to the dryer receptacle? I will get either a simple 240v timer or a contactor with a 110v coil for timing.

Is this safe?

Consult your building electrical code in your area.

It's not per code because the dryer circuit is 30a. This would be like a convenience outlet, but at the same time, having a 30a breaker on a 3a load is over-protecting it.

I understand the code, but we are often using load panels to connect multiple lights with a single hardwire.

I guess I could run a new 15a double-pole breaker.

I also found this. It would seem that with this, I could run a single double-pole breaker and support 110v/220v in the same receptacle.

It will work fine. The 3 amps is not much load, just be sure the dryer is not turned on at the same time.

Sounds like a good idea, or a pony panel. I agree it would be okay and it sounds like your okay with the code. Just make it easy to remove should there ever be an inspection or you need to move and do the same thing elsewhere.
