And off when it says on. What's up with that? I never noticed because I just flip it when I need to. If you look at the vom, it says mv.

not 300v, 300mv random reading. The on and off are written on the breaker itself, so upside down or not, it shouldn't matter.

Can u post a pic that is zoomed out? I cant see where youre reading from...

The meter shows mV to me thats phantom voltage and NOT indicative of the breaker being on. My fluke has done that before...

The reading is typical for my vom with no voltage, but the breaker is on. When i turn it "off" it reads 220.

First off the breaker labeling is wrong. By code a vertically switched breaker needs to be OFF in the down position and on in the up position. However, the breaker IS off in the down position....looks like just a labeling issue!!

What brand of breaker is that? I dont quite recognize it...

It on when up and off when down, just labeled wrong. Seems unsafe to be labeled like that, even if it's up to code.

That panel is stuffed!

How many spaces and circuits is that panel rated for, it should say inside the door? 20/20, 20/40, etc?

Ummm, a lot, hopefully 32 different ones. Don't really care to check. It was a battle getting the new breaker and #2 in.

I think that is a Zinsco breaker, which could explain a lot!

Could it be that just the small plastic piece under the double handle, with the ON/OFF etching has been installed incorrectly?

I agree,that black peice is upside down not the breaker

I cant stand those panels with the small space for wire...

If the main IS a Zinsco, the panel doesnt look to be Zinsco...

Had a customer that wanted me to change out a panel smaller than that with the same small space for wire on the right. Unfortunately, like the OPs its recessed in stucko and would have been a PIA and exprnsive to change...

I think the main breaker has a metal locking device over it for a padlock, which was installed upside down. Remove that and I bet the breaker is labeled correctly.

The panel is a Challenger or Westinghouse BR, they both used a Zinsco design main for 200A, one would hope that the breaker escutcheon is reversed,as said by others just reverse it to get the correct ON/OFF markings.

Challenger, and Westinghouse, BR panels were the same since Westinghouse owned Challenger, and Challenger, was a Zinsco/Sylvania successor, hence those infernal Zinsco mains.

300 mV is leakage, less than a 1/3 of a volt. Probably capacitive coupling.

None of you have VOMs that display phantom voltages with no connection? All of mine see to do that. It will read 0 if I go ground to ground, but when there is no connection is just drifts around in the mV range.

Absolutely! I use my trusty Triplett (http://www.triplett.com/shop/model-630/) if I don't want to be bothered by this.

You're basically connected to all that wiring in the house, a big antenna! :bounce:

If you look at the breaker trim, surround, lock out, whatever you want to call it, the stamped labeling is such that it can be read in both positions. I'm not an expert but I'll 2nd that it can be flipped around and all is good.

But on the other hand, Challenger was the successor to Zinsco/Sylvania. :D GTE sold their Electrical Equipment Group in the early 1980's & it became Challenger, who was later acquired by Westinghouse they rebranded Westinghouse/Bryant breakers as Challenger which continued until the Westinghouse electrical div. was bought by Eaton, who sold Challenger to T&B...

In my humble opinion, Zinsco is only half of the name of the subject circuit breaker.

Their whole name, as they are called by electrical journeymen of my acquaintance is "F___ing Zinsco".
