Tandem breakers

[Daniel Robinson]

I have never seen a breaker like this I think it is a tandem breaker. Square D box. House was 35 done years old with up grade to box done recently.
:confused:

Yup, they are old style tandems. You can't use them in new boxes, only for replacement in existing installations.

Thanks that what I thought.

That panel is original to the house. It was NOT "upgraded" ever.

Agreed based on the small wiring gutters and the rust.
