House built in 1953. Has 2 - 100 amps "indoor" Federal Pacific electric panels, one in each side of the house. Both have neutral and ground bonded at the panels. Each one has outside fuse 100 amps disconnects and below is the gutter (btw indoor type) that contains the conductors from the meter to those disconnects and that neutral and ground are bonded there as well with also the ground electric conductor AWG 6 that I assume goes to the water pipe. There is a "small subpanel" that was added at later time for the AC and the pool and this was illegally tap on one of the disconnects and this sub has also the neutral and ground bonded. Really a Jumbo Mumbo situation. Those panels are in a very good condition and there are no money to replace those. I will replace all switches and receptacles and add GFCI where needed as there are none. WHY, in 1953 they bonded in 3 locations the neutral and grounds (in 2 panels and the gutter)? Maybe those panels were treated as "service panels" but then why the bonding at the gutter? I have 9 pictures but for some reasons the forum doesn't allow to download them
