Hi Albert,
If you are worried about the wire temperature, then purchase a few of these from Grainger for testing. https://www.grainger.com/product/TEMPCO-Swaged-Cartridge-Heater-100-4NJA4. You will then have to modify the heater aluminum plate as shown below to accommodate the larger size. You should also purchase some ceramic wire nuts (https://www.grainger.com/product/TEMPCO-Ceramic-Wire-Connector-White-36D140) or something similar for connecting the heaters. I already have high heater fiberglass electrical tape.

Hi Marc,

I've looked at the heater's data sheet and can't find
any details on what temperature can operated  wires?
Please let me know about wire temperature?

Thank you,
Albert
