Do you open stab-lock panels?

[Mark Sylvester]

How many of you if any open federal Pacific stab-lock panels?
In my case I never do because of the way the breakers overlap the panel cover.
Does anyone finagle the cover off to actually check the wiring?
In my case I just explain the facts about the panel and explain why I don't pull the dead fronts off of them.

I'm always curious of what I would find if anything.

[William E. Siegel]

Unless I can definetly tell that the breakers are loose, I open them all up.

[Mark Sylvester]

Do you ever trip the breakers?

[Greg Bell]

I almost always open an FP. I never open a Zinsco.

[Mark Sylvester]

I have tripped the breaker several times while taking the panel covers off so I tend not to pull them. I should also explain I always find these panel in condos tucked up under the kitchen cabinets with very little room if any to move the cover up and over the breakers. The picture is of my latest one that had other problems as you can see.

There are less problems with opening Zinsco's. Man-up Greg

I open all covers unless there are obvious safety concerns. I occasionally trip breakers, but that's just the way that it goes. . .

Every one when I can reasonably access.

Greg,
Why not Zinsco?

This one was accessed though the inside of a cabinet about a foot inside a 12" duct chase and near the end of my arm. The panel had been built into the chase back in '67-'72 when the kitchen was remodeled. No way was I going to try and remove the cover. I wondered who added the GFCI?

Client: "What needs to be done?"
Me: "Consult a carpenter and an electrician for the cost to relocate to an accessible location.
Client: "Why a carpenter?"
Me: "Have you ever seen an electrician tear into a wall to gain access?"
Client: "NO?"
Me: "The only thing worse is when a plumber does it."

They got the picture

[Jim Port]

If you were to open the panel up due to the design of the buss stab it is quite possible that some breakers will just fall out of the panel. At this point you could see any hot spots or deterioration of the buss.

If I did not open FP panels I would not be opening very many at all 75% of all panels in my area are FP

[Frank P. Newman]

While perhaps bordering on a violation of the SOPs does anyone just trip the main breaker(s) before pulling the cover off of such panels? I would think that would be preferable to not inspecting the panel at all.

Not in an open forum and how would this violate SOP?

Maybe exceed, but violate???

[David P. Valley]

I open all FPE panel dead fronts unless obvious safety issues are present.

They're aren't many electrical panels that get by me without being fully accessed.

We don't have Zinsco's here in Massachusetts.

Your 'exceed' may be more correct. I guess I was referring to...

2.7.II. The inspector is not required to:
D. Operate overcurrent devices

In any event I think it would be a good, safe practice any time a panel looks or 'feels' suspicious.

[Linda J. Foster]

We usually open all panels, the exception is FP and it depends on how accessible it is.

On tripping the main before looking, what if Grandma is upstairs in an iron lung?

I don't unplug / turn off anything.

Think of safety first !

Man, I hate when that happens

I did manage to get somone mad at me when I accidently dumped the circuit his computer was on. It was a reporter writing an article who had not backed up recently. oops! sorry 'bout that

Let's just say he wasn't happy about having to rewrite it. Everyone seems to learn the hard way about backing up frequently.
