The income section of a LV switchgear (line-side of main OCPD) has a incident energy of 65 cal/cm2 (Dangerous).
The adjacent section (load side of OCPD) has a incident energy of 3 cal/cm2.
The switchgear is open frame, so there is no barriers between both sections.
What kind of label would you affix to this switchgear?
Options:
1. Only one for the whole panels (incoming and feeder sections) with the AFIE of 65 cal/cm2.
2. Dual label, for incoming section 65 cal/cm2 and for all feeder sections 3 cal/cm2.
3. Other solution.
The problem arises to be so close to a high incident energy area using only PPE of 3 cal/cm2.
Thanks.
According to some interpretations
operating the main breaker would be illegal because you are above 40Cal/cm2. Working so close is probably no safer and could be more dangerous.
