This old Push-Matic panel was well overdue for an upgrade.
I arrived at this house with many things no longer functioning properly after a power surge. Started troubleshooting with the obvious items and it wasn't long before I found a few of the old Push-Matic breakers had tripped and ultimately failed due to the recent power surge. These breakers are notorious for tripping and refusing to reset. This is actually a best case scenario. These particular breakers are really better known for failing to trip altogether resulting in bad electrical issues including failed wiring and the potential for a devastating fire.
This day I proceeded to remove the old damaged panel with a shiny new version and the customer couldn't be happier.
