Removing 1/2 of MWBC (one phase)

A picture of the panel would be nice.

For the record, I'm like ptonsparky, I've never seen a 46 space panel in the late 90's. With a #23, that would indicate at least a 46 space panel.

Through the 1999 code lighting and appliance panelboard were limited to 42 circuits.

That's what I thought. I didn't remember exactly when it changed, but knew it was in that era.

Would be good to see how the bussing and breaker placement is.

Come to think of it, isn't 1929 early for breakers anyway? Wouldn't it have been fuses?

If this is K&T and you are updating it at receptacles to provide a ground, why aren't you doing a home run back to the panel? If not, how are you getting a ground wire there?

The OP says the wiring is from the 1920s, he does not mention the age of the panel nor how many circuits are in it.

It could be 24 circuit. 24/30. IDK.

He said the panel was replaced in the early 1990's. That's why we questioned having a circuit #23.

I missed that in post 12, but where did the number of circuits come from?

Typical numbering is odds on left, even on right. 23 on left would indicate 46 circuit panel.

Since a panel has odd number circuits on one side, and even on the other, we just figured when he said circuit #23 that there would have a even number #46 on the other. Of course he didn't say what kind the panel was, so it could just be one row of breakers.

Stop typing faster than me!

Not if it was a Pushmatic panel.
I am not aware of any residential panel UL listed with more than 42 circuits built prior to 2010ish.

Sounds like non-CTL tandems have possibly been added as others are thinking. Of course this is a violation.

oops, sorry
