Shrink tunnel voltage conversion

Hey guys, new here, and have what I have to believe is a stupid question to ask.

What happens if I wire a motor that only has 115 on the face plate for 220? I've got a heat shrink tunnel with a 115 motor, but I need to upgrade the heating element to 220 for a higher temp output. The heating element is compatible with both voltages, but I don't know how I could wire it without burning up the motor.

Any ideas?

Connecting anything, (motor, heat element) to a voltage higher then what it is rated/designed for will likely destroy that piece of equipment.

If the element is duel rated to take 120v and 208-240v then the answer is to run another hot for the 240 volt loads and keep the neutral for the 120 volt load. Basically you need a 120/240 volt circuit.

Welcome to the forums.

Not a stupid question.

You're talking about upgrading the heating element to 240v. That's not an upgrade. That's a complete modification. Your device came wired for 120vac. Now you are modifying it for 120/240v. That means you will need a four wire cable connecting it to power.

A motor runs only on its rated voltage. If it says 115v..... that's it.

Do you understand the 120 to 240v conversion process ?
It needs to be done safely.
What are the controls like. Are they designed for 120v only ?
