Hi Guys,
I posted this thread on the code issues forum about a week ago, seems those folks are asleep so pardon me for putting it here as well.
I have a large electrical immersion heater (120kW) in Class 1 Div 2 location. The terminal box is NEMA 4. The manufacturer claims it is suitable for Class 1 Div 2 under NEC Article 500 because "It's considered a npon-sparking device" I suspect it needs to be NEMA 7 or purged.
I need to somehow satisfy Korean KOSHA authority.
Interested to hear what others think.
Thanks
Roy
