Default 30ma gfci

I need to hook some heat trace up and need it protected. I’d assume a 4-6 gfci breaker would have nussiance tripping. Is there a cheaper way to achieve 30ma or just find the breaker That’s meets this ?

Not sure what heat trace is---is it the same as heat tape? Does the stuff plug in? If it is a plug in you have no choice if the receptacle is in an area that requires gfci. If it is direct wired then you don't need gfci unless the instructions call for it.

Floor heat has gfci protection in the T-stat so I am not certain about what you have

Is this a commercial application or residential? I have installed hard wired heat tracing on 8" chiller pipes on the roof and used regular GFCI breakers without a problem. It was a system with T-stats and indicator lights. But then, I have not been back to check on it. I would try the GFCI for personal and if it does not work then look for the GFCI for equipment. What did the instructions say?

Just about every heat trace I've installed has 30 ma GFI breakers. Very rarely do they trip, if they do, there's usually a problem somewhere.

We've got a fair amount that has never had a GFI breaker on it, some with 5 mA breakers and the rest (obviously) is on 33 mA Breakers. I don't know that the 5 mA trips any more often than any other. Typically, when there is a fault it will trip the breaker regardless of the GFI rating. If there is only a bit of moisture in an end or power kit, that might make a difference.

Depending what it is for it does need GFCI protection, for example, 427.22 requires it for pipeline and vessels. Likewise, 426.28 requires it for snow melting and de-icing equipment.

It does NOT however specify class A (which is the 4-6mA trip) as the protection for receptacles does in 210.8. This means that a 30mA device can be used (IIRC this is class E protection).

Old parallel CH BR afci breakers were clearly labeled on the side as having 30ma ground fault protection. That is the only time I have ever willingly installed an arc fault breaker. Gfpe breaker for a third of the cost
