Re: Electrical Panel replacement.
The question has been asked, ?When should I replace an electrical panel that is not the cause of but involved in a structural fire??
While this must be decided on a case-by-case basis here are two ?must? replacements of the electrical panel.
1.) ?If there are any signs of moisture or damage the equipment should be replaced or repaired, as previously described.? Source Square D Product Data Bulletin Class 110 October 1995.
2.) ?If an oily substance is found.? Source Square D Product Data Bulletin 0110DB0301 July 2003.
?Electrical equipment manufacturers are contacted occasionally about an
oily residue found on the surface of circuit breakers and, sometimes, control
equipment. An investigation launched to identify the source of the oily
substance found that the oil comes from the degradation of the PVC
insulation used to insulate some circuit conductors. Given sufficient heat
and time, the oil plasticizer separates from the PVC material and wicks to
the circuit breaker, resulting in an oily accumulation on the circuit breaker
surface and embrittled insulation on the conductors.
Failure to replace electrical panels that have been subject to water, smoke, or heat damage is contrary to the listed equipment requirements. Not withstanding the potential safety implications, this is a violation of the 2002 NEC Article 110.3(B).
Although some areas have not codified the any edition of the NEC all parties involved should be made aware of the safety hazards present by not following the manufacturers listed equipment requirements.
