30 ma GF Protector

[augie47]

I inspected a job where some heat trace was installed without the required (427.22) GFI .
The tape is in a Class 1 Div II area and the breaker supplying it is foreign.
Does anyone know of a in-line GFI device that can be added in line at the panel ?

Page 14 has high current and panel mounted.

Thanks, but I'm looking for the 30 ma GF protection for heat tape installs.
Those were 5 ma GFCI, I believe.

I have heard of Class B GFCIs, but I have seen a device or breaker. Is it possiible they are obselete? IDK

In a previous life, I used Technology Research Corp for >5mA applications.

Left out a word, I have not seen a single Class B device.

The note at the bottom of page 14 reads.

Note: A panel mount Equipment Leakage Circuit Interrupter (ELCI) is also available.
Contact your Leviton representative for information

Thought that meant 30ma.

ASI sells a supplementary DIN rail mount GFPE breaker that you might be able to use. Try http://www.asi-ex.com

I suspect you will find that the manufacturer has their own GFI cordset that they specify be used with their product. That part would be the 30mA GFCI.

A summary od GFCI reasons, ar referenced in the NEC:

5mA: Personnel protection

20mA: Old pool lights

30mA: Equipment protection
