240 to 120?

[BigJay13]

I've been looking at RIMS tubes that are prewired for 240 and I want to run them at 120. If I have something that is prewired already, is there a way to run 120V power to it without rewiring the element enclosure itself? IE a hotpot or something similar?

You can run a 240V on 120V directly, but it will only run at 1/4 rated power.

I guess my real question is, if it is already wired for 240, how do I put it to 120? I'm not idiot with electricity I just am not familiar with the different kinds of plugs and connections.

Connect it to a hot and neutral, rather than to hot1 and hot2.

Wouldn't it run it at 1/2 rated power? since it is only getting half the voltage?

Don't take this the wrong way. It is very possible that I am looking at it wrong. Self taught electrician ( the worst kind wright)

Watts= Voltage squared divided by resistance.
So then running at 1/2 voltage results in 1/4 power.

Open up the plug end. Its 4 wires (ground, Neutral, Hot 1, Hot 2), Replace the plug with a 120v plug and only use 1 of the hots. It will just apply 120v to the element instead of 240, and you'll get 1/4 the power
