Class I Div II Area and 24VDC
Class I Div II Area and 24VDC
(OP)
I have an IS 24VDC transmitter located in a Class I Div II area. It goes back to a NEMA 4 junction box some 10' away. There is a 24VDC terminal strip in said box - nothing more nothing less. The conduits entering/leaving box have seal-offs poured. There is also a seal-off at the device. I am told the J-Box must be Class I Div II explosion proof. Is this so? Thanks.

If the terminal blocks have components in them that could arc or spark if they failed, then the blocks have to be rated for the area, or it has to be in a rated enclosure.
