Our mechanical engineer specified heat trace to be installed within the underground storm on a commercial building. The electrical inspector is concerned that when a plumber snakes the pipe he will get electrocuted. I figure the ground fault protection would keep that from happening, but admit that it is very possible the pipe gets snaked someday, and that the likelihood of heat trace coming out from that unscathed is not very good. What is common practice for heat trace installed in underground storm drains?
