Is there any type of inline circuit breaker that i could use to plug a 220v 15amp device into a 220v 40amp outlet? I know it isn't code, but I don't feel like wiring a whole new outlet and circuit.

A circuit breaker is an inline device. I don't see any reason you can't install a smaller ckt breaker inline to protect a smaller device. It's done all the time. Look at your breaker panel....you have a single big breaker protecting all those smaller breakers.

Guessing I'm asking where I would find a circuit breaker that isn't designed to go in a panel box? One that I can either wire to make an extension/adapter cord. I know it will work, just not sure how to find one?

I'm guessing whatever device you are plugging in doesn't have any overload protection of its own? Circuit breakers are designed to protect the wiring in your house- not whats plugged into that circuit. You are looking for a 240v power strip with a circuit breaker built in.

Dryer outlets are not grounding type receptacles. (They have 2- ungrounded (hots) & a neutral).

First, the breaker in the panel is designed to protect the building and its wiring, not the end device.

All end devices that plug in must have, built in, so means to be safe when connected to the A/C supply. There are a zillion rules (including UL ones) that cover this topic well.

There should be no reason to add an additional breaker to a device under the circumstances you describe. But if you insist, you can do it as described in the other posts.

This is no different from plugging in your laptop computer (that only pulls maybe 1 amp) into your wall outlet that is rated 15amp.

Don't worry about it.

For 10 years or so, any new dryer you'd buy today or any new house wired for a dryer is a 4 prong with ground. And older home is grandfathered in to use 3 wire and a new dryer can be converted easily but the newr standard has been 4 wire since about 1999.

The one pictured was not one meeting current code requirements. BTW it was NEC art. 250-60 in the 1996 edition that finally got rid of grounding the frames of dryers & cooking equipment through the neutral.

What is the "device" you are wanting to plug into this circuit?
