Cartridge style fuse size

[Michael Thomas]

Any way to determine the size of this fuse without withdrawing it?

[David Banks]

None that I know. If it is the Main I ask the Owner or Realtor to call the owner and ask if it is OK before I pull the Main. Also check for any computers.

[Phillip Stojanik]

You don't even know if there are fuses in it at this point. You could pull it and find the fuses have been replaced with a couple lenghts of copper water pipe. Stranger things have happened!

[Jim Luttrall]

Any chace that is just a disconnect without fuses, similar to A/C disconnects? I have not seen that particular style before.

"Any chance that is just a disconnect without fuses, similar to A/C disconnects? I have not seen that particular style before.?"

I hope not - that's sitting between the meter and a (maxed out) 30 breaker load-side panel with no main disconnect....
