appleton makes a pretty nice explosionproof threaded LB. probably costs a pretty penny101010 said:Also , I have to put an lb to leave the classified area , I am planning to put a seal before the lb , Is this ok or should the lb be put before the seal and a seal on the unclassified side? When sealing around the penetration that I have to make trough the wall , is duct seal all I have to put? Does the Lb have to be explosion proof? Sorry but I dont do much haz loc work .
Most likely the junction box is much more expensive.101010 said:explosion proof junction box cheaper?
