Exproof junction box in an explosive atmosphere
Exproof junction box in an explosive atmosphere
(OP)
Hi all,
We have a junction box to be used for a plant at a natural gas rafinary. The box originally was an ATEX certified one. But we needed to drill a hole for 10* cable. We will use ATEX-certified gland for cable entrance. The thing I wonder is;
"Does the ATEX approved property of the box still valid?"
"Can it cause any explosion or sth dangerous in the future?"
I need your eng-tips.

The box is manufactured by a local workshop and I don't have a written document of certification.
"Don't we have any other way to determine its safety?"
Also the construction site we work is "Zone 2" which I think does not need such high certification. I am confused about this. What do you think?

You shouldn't accept the equipment without the certificate. Do you know if it is Ex 'd', Ex 'e', Ex 'n' or something else?

The box contains terminal box for connection of 12v signals. Will it be ok to use ATEX certified terminal boxes instead of changing the junction box?
