We are installing a pipe trace system on plastic piping in an underground parking garage. What concerns should I be aware of?

 

Apr 16, 2018

First of all you need to be aware of Section 62-308 of the Canadian Electrical Code. Heating cables on non-metallic pipes require a thermostat on each pipe: “A heating cable set or heating panel set installed on a non-metallic pipe, duct, or vessel shall be controlled by a thermostat or other suitable temperature-limiting system so that it does not cause damage to the pipe, duct, or vessel.” Using one ambient air sensing thermostat to control all of the pipe tracing on separate non-metallic pipes does not meet the letter of the code.
