It's hard to answer this question based on the information given. This switch is suited just fine to switch power on devices that utilize power up to 30A at 240v.

Answer: 
Hello,
I would recommend that you speak to an associate at your local Home Depot or consult a professional electrician to take a look at your specific application. There are many questions that need to be answered that only someone who can look at your application will be able to answer.

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Excellent disconnect I used this disconnect for my 220v air compressor in my home shop. This box was inexpensive, good quality, was easy to install and performed flawlessly. Not much more to say about it. It does the job well and I'd certainly recommend it for a similar application. December 14, 2015
