I would like to learn more about electrical control for Explosion proof room.
Any advice ? or good place to learn that?

The little i know about it is all panel or light etc have to be certifified for this kind of room, and the control seem to be controlled by the neutral rather than the hot one.

I got a section i saw on my electrical code that im going to read but i wont know alot about how to make control etc.


Thanks !

(I need this because where i work we got a room F1 with reactor and mixer but other electrician made alot of control using that kind of wiring even outside these special room).

If it sparks, you need a seal.
When you leave the classified area, you need a seal.
When planning your pipe run, remember, the pipes with bends thread together, not slide into connectors and couplings, so plan carefully.
UNYs are expensive, so try to use as few as possible.
And when running rigid, cutting oil gets on everything.
All the above makes it much easier to use Teck with XP fittings:thumbup:

Use the right fittings for the application... Know what Class you are getting into before you start..Sometimes a gasketted fitting will work, where in others you'll need GUA fittings..
Remember about your grounds.. Condulet fittings don't typically have a ground screw, which is why most guys will pull a ground wire..
Plan where you are going to put unions and splice boxes.. Sometimes an extra box and union will make equipment removal easier in the future...
If you're not sure - ASK!!! You aren't the first one to use such wiring methods and lots of guys can help...

That's exactly the type of advice i wanted thanks guys !


But for the control is there anything else to remember than trying to control with the neutral than the hot one ? the PLC and input seem to be prety much all NPN or something
