I have an old 225 Amp 30 space commercial flush mount sub-panel in my home with bolt on breakers that has worked for years. Now, there's 120v on one bus and 0 volts on the other bus.
When I remove the leads from the bus, I get 120v on each lead, so there isn't an issue with he wire. It seems I have to replace the panelboard, as when I attach one the lead to the bus the voltage drops from 120v to 0v (the other lead is fine).
I can't seem to find a replacement panelboard for an I-T-E NLA30-3L.
Does anyone know where I might be able to find a replacement?
Are the panel boards repairable?
Is there a replacement panelboard perhaps from Siemens or any other company that will accept the same I-T-E bolt-on breakers so I don't have to replace all of the breakers?
