Older fuses for main and range, etc.

Does the one pullout kill "disconnect" the supply?

Is this diagram from an old 1959 book misleading?

Hi Joe,

I have a theory on these and every panel that I've seen has borne it out. However people from other parts of the country have told me that my theory doesn't hold in their neighborhood -- yet no one's ever sent me a picture to disprove it.

Here it is:

There were two different types of fusebox that had this very same arrangement of two pullout cartrige fuse blocks at the top and four screw-in fuses at the bottom.

  • The boxes that were rated at 60-amps fed the range block from the load side of the main block as the one in your schematic shows.

Alternatively, the ones that were rated at 100 amps fed the range block from the line side of the main block as in the attached schematic.

Do you agree?

I did an estimate on this for a service upgrade for a real estate agent.

Sad thing is, the prospective homeowner thought it was OK. They didn't want an upgrade.

Good luck with homeowner's insurance.
