[i][b]Hazardous Areas, & Terminal Blocks[/b][/i]

[TTheHammer]

Hi All,
I guess this will be abit long, I'm designing the controls for a regulating station for a Class I Div I location, and all of the inside instrumentation are exiting via a terminal block then going to the control building. my question is :

Can I connect also the field equipment (which is outside the Class I Div 1 area) to the same terminal block (in Class I Div 2), then pull everything through one conduit to the control building?

Or you think that I should have a seperate conduit for field equipments?

Thanks Guys

A better place to post your question is the NFPA forum, forum184. Also, do a search on "intrinsically safe".
