AC WORKS®: The Two T-Blade Plugs

Posted by Christopher Hahn on

Lately, we have had quite a few customers contact us to see if they can operate their 250 Volt AC units from a household outlet. They try to use a household adapter such as M515520, which won’t work for this issue. Why won’t it work? Can a 250 Volt AC unit be adapted for a household outlet?

It won’t work because the AC unit you have most likely has a NEMA 6-20 plug on it. This is rated for 20 amps at 250 volts, whereas a NEMA 5-20 outlet in your home is only rated for 20 amps at 125 volts. The difference in voltage won’t allow your AC unit to kick on. The AC unit needs 250 volts in order to work.

In this video, you will learn the visual and technical differences between two of the most mixed-up T-blade plugs; NEMA 5-20P and NEMA 6-20P.
