In the past, we discussed the differences in 125 versus 250 Volt air conditioner connections. The two different connections are also shared by portable heaters. So let's review:

The two different connections look very similar, but have one major difference; their operational power. The NEMA 5-20 is rated for 20 Amps at 125 Volts, while the NEMA 6-20 is rated for 20 Amps at 250 Volts. There’s a difference in voltage, big deal, right?

Yes, it is. If your portable heater has a NEMA 6-20 plug, that means it requires the full 250 Volts to operate effectively. You cannot adapt your 620 heater plug to a household outlet! If you try to do so, your heater either won’t provide enough heat or won’t work at all.

Learn about the different outlets available in your home or workshop that you can adapt to power your 250 Volt portable heater.

If you are unsure which plug your portable heater is equipped with, send us a picture of it and we would be more than happy to help! You can also send images of the outlets you are trying to adapt to, and we can let you know if it’s possible. You can reach us with a phone call, text, or email.
