Can self-regulating heat trace touch itself?
Constant wattage heat trace and MI cable cannot cross or touch itself. Self-regulating heat trace cables, however, would adjust to this temperature increase, making them safe to cross or overlap. As with any electrical system, though, there are always potential dangers with using heat trace or heat cables.
What is self-regulating heat trace cable?
Self-regulating / self-limiting heating cable, often called heat trace cable or heating tape, automatically adjusts heat output based on surface temperature. Ideal for freeze protection and low temperature process maintenance such as water pipe heating and roof & gutter freeze protection.
Can heat tape be spliced?
Use this kit to make a splice or tee connection. For use when you need to branch custom-length heat tape in multiple directions to achieve complex configurations using a single heat tape power source.
Does heat trace require GFCI protection?
Electric heat tracing (heat tape) requires ground-fault protection of equipment (GFPE). It also states that they have not been investigated for providing electric shock protection for personnel or are suitable for use where GFCI protection is required.
Does heat trace need to be insulated?
If you can see the pipe at any point it MUST be insulated. Wind-chill and extreme cold ambient temperatures are the main factors that lead to heat loss, causing your pipe to freeze even when protected by heat trace. Being in a boxed enclosure or big-o drain pipe is not enough protection, it must be insulated.
How long does a heat tape last?
Speaking of replacing, heat tape only has a 3-year lifespan. Most heat tape manufacturers warn that you should replace your heat tapes every 3 years minimum. Heat tape has a near-constant connection with both water and electricity and usually isn’t protected well from the elements.
