By the way Ray,
What is that green material?.
Is it like a plastic?

Underneath the fuses?
Thats just light green A 4 paper.

That green stuff underneath the 5 pack of 16 Amps diazed fuses is the packing material.

Thanks for the quick posting Mike.

Nice pictures! I noticed that there is a mix of "resetable fuses" and conventional fuses in the box.

For comparison, here is picture of Diazed fuses in sizes I to IV.

Hi Rodalco,

Nice to see that very old Holec switchgear :-) It must be at least 45 years old.
Normally the fuseboard would be assembled so that the circuit switches would be on top of the circuit fuse.

Strange setup, didn't see that one before.

I must say that the main switch you use is common known for faulty contacts, sometimes it doesn't switch a pole (which could be your neutral, which would be offcourse catastrofal).

Groeten (Greetz),

Arend
