I recently bid on a project for a 4 story addition to a bank building.

The switchgear was a 30 year old Federal Pacific 1200A panel with two 600A fused switches. The engineer had specified a new 1200A GFI main breaker to be installed in the old switchboard.

The only way to accomplish this would be to fabricate the mounting system and the sheetmetal required to enclose the front of the switchboard. Are these types of mods normally done?? Doesn't field modification violate the equipment listing?

Would you allow this in your jurisdiction if it was done under engineering directive?
