Junction box certifcation for internsically safe circuits
Junction box certifcation for internsically safe circuits
(OP)
Dear al
I have procured EEx certified SS316 JBs with normal color terminal blocks and valid certification is EEXE
Now the 2 or 3 of my circuits are changing to Is
Can I use the same junction box by changing the terminal blocks to Blue, and making extra tag plate to indica IS circuits inside in blue color
Or I need to get it recertified to EExia
Please comment and give the technically best solution

2 or 3 JB will be dedicated for IS circuits only
But y question is only the certification , Is EEx E certified JB cn be accepted for Is circuits
or
Do I need to re certify the the JB EExia ib
RE: Junction box certifcation for internsically safe circuits
Ergo, you're likely to need a separate JB just for the IS circuits only, which in turn renders the original question moot.
RE: Junction box certifcation for internsically safe circuits
Your comments well noted. The IS circuits are on a dedicated JB which has only IS circuits
now the next step is whether the JB need to be re certified for EExia ?
or EEXe certified with blue color terminal blocks (eexe ) and blue warning label on the cover will be accepted
