White paint in electric panel ?
Hi everyone,
I have never seen white paint inside an electric panel. Could that be any other stuff to protect the wires or breakers...it looks like paint to me because all the appartment was recently painted white...
Lets assume their was not cover on the panel and they painted the inside, why are the breakers still black (if its the case) ??

Re: White paint in electric panel ?
Good question as to why the breakers are still black. Would like the answer to that one also. As for the paint - well now they need to replace the box, or at least, they should. No foreign objects are allowed inside the box and you cannot use abrasives to clean the inside of the box. Did you also note the improper termination of the ground wires?

Re: White paint in electric panel ?
It's baffling how part of the CB's are still black.
What's the problem with the EGC's?

Re: White paint in electric panel ?
They spray painted the walls of the house and did not cover the panel. Why the breaker handles are not painted is a mystery but does not really matter. My guess is that they were painted at one time and have been cleaned by someone who thought that would make it all better.
In the eyes of the panel manufacturer and the electrical codes that panel and breakers are damaged and now need to be replaced.
The paint can prevent a good connection between the breakers and their point of connection in the panel. Also the paint can prevent a breaker from tripping.

Write it up for replacement.
I'll let a little overspray slide but that's too much paint. Let'em sue the painting contractor.

Many EGC bars are listed for 2 or 3 conductors.

Those breakers were white when they left the factory. Pic 3 and 4 you can see where they masked the breakers, different shade of white.

Re: White paint in electric panel ?
Agree, looks like factory colored breakers. But the box has still been painted and since the cover is clean.........just weird. Sometimes it is tempting to write, "Not sure if this is wrong or not, but definitely goofy".
I just inspected a house for my brother in law. I wish I had thought to say that, because I saw several homeowner modifications that fit that description and I could have gotten away with a little inspection humor with him.
And.......doesn't that look like more than six breakers to turn off service.

There may be a disco eleswhere, & does anyone have commentary or code sections from the CEC? The NEC is irrelevent in this case.

Re: White paint in electric panel ?
In Canada, there can only be ONE main disconnect. There is no 6 breaker rule in the CEC.
That breaker panel is in an apartment in Montreal, which is the same as a condo. The main breaker is down in the meter cabinet, so there is no problem there..
The neutral should not be bonded, but I can't tell with all that paint.
I believe the installation was fine until those goofs came in to apply the fresh paint. I don't have the rule for whether paint is allowed on the wire connections. In Quebec, they write their own rules en francais, anyway.

Re: White paint in electric panel ?
A breaker lock will still allow a breaker to trip so I doubt a coat of paint would stop a trip.
The connections were also made before the paint was applied so there should be no need to worry about the buss connections or the conductor terminations at the breakers.
All answers based on unamended National Electrical codes.

The breaker handles were coated with vaseline prior painting.

Re: White paint in electric panel ?
It looks like there is a small ground bar on both sides of the panel as long as all the grounds are connected it looks good to me. Paint won't interfere with how the panel works.

Re: White paint in electric panel ?
One of the interesting thing about "paint" is that it may contain a number of "suspended" solids, some of which may be conductive in nature, and quite a few which may be "insulative" in nature, which when cured form a layer.Wall finishes (paints, primers, etc.) actually burn.Additionally "paints" dry or cure with evaporation of their carrying medium. Chemical reactions to nylon coatings, plastics, etc. can damage, even if the damage doesn't seem readily apparent to the naked eye.Paint in a panel, on MCCBs, BUSSes, terminals, etc. sprayed so copiously is detrimental to the safety, ratings, function of the screw terminals, etc. it is foreign, untested, unlisted, material, that negates the UL or CSA listing/approval of the equipment, voids any warrantees expressed or implied and is a violation of the CEC and for those south, the NEC.Consider something as simple as high carbon content suspended solids in "high hiding/blocking primers/paints (along with say lots of "white" solids as well - zinc oxide for example) not only possiblity of conductivity (high carbon content) but disimilar metals contact and oxidiaton creating high resistance connections - heat. Further a panel is designed and limited based on ability to function and put-off heat and maintain integrity of the panel itself, and the installed equipment, withstand and contain events without spontaneous ignition, etc.Add to that the insulative (heat traping) and moisture/vapor transfer resistance of a "paint layer".Painting over labeling at side of CB also adulterates CB.Foreign material (finishing material, i.e. paint) doesn't belong in the panel, period. Painting CBs is not permitted, the film upon the CB has not been tested regards deteriorating agents, insulation load (over heating) air sealing, functionality of breaker as a switch, chemical, particulate matter, interreaction with the breaker's LUBRICATION media, conductivity of surfaces, etc. nor the remaining film's flamability, flame index, smoke index, etc. Paint coatings on the buss bars and terminals, terminal screws not allowed. Compromise foreign matter within connection, terminal screws, lugs, makes accurate determination of proper torque questionable, and low-resistance connections questionable.Add to the mix an obsolete panel in the first place and you've got legitimate safety issues that the ESA would likely condem.

Re: White paint in electric panel ?
I have never seen paint hurt an electrical conductor but I may be wrong. I really don't understand why painters can't be more careful. Just putting some cardboard in there could have prevented this. Myself if someone requested I do something with it. I would remark all the wires replace the panel interior and breakers with a modern brand put the new cover on call it done. Mostly because nobody is going to want to pay for the cost to demo the building install a new panel and fish all new home runs or deal with junction box covers all around the panel with splices.

Re: White paint in electric panel ?
The inspector, Christian, wants to know how to proceed.
Here is my advice on this one, JMO:
Identify the problem - Fresh, most likely latex, paint on the conductors, the panel and neutral and grounding connections.
Inform the client of the implications - There could be issues, as mentioned above.
The ultimate decision as to whether there is a defect here or not will rest upon the local authority, an inspector for the provincial Electrical Safety Branch of government. Ask him/her.
An electrical contractor can apply for a permit to repair and get the info that way, or the seller, the buyer and their agents can try to find an answer directly from the authority. Or the inspector can offer to find out, and if he does, he can let us know how it went.
This painter needs to be brought into the equation, because it is bad practice for him to run around town painting panel interiors.
Twisted EGC's is a non-issue on an installation that received approval 20 years ago. It is a multi-residential in Montreal, and you bet the permits are all there, signed and stamped. Count the breakers and then count the number of grounding connectors provided by the manufacturer. They don't add up. If somebody wants to pursue that as a defect, they should do it on their own dime, not the client's. JMO.

Re: White paint in electric panel ?
Bottom Line - NEC 2008 Section 110.12 (B)
Integrity of Electrical Equipment and Connections:
Internal parts of electrical equipment, including busbars, wiring terminals, insulators, and other surface, shall not be damaged or contaminated by foreign materials such as paint, plaster, cleaners, abrasives, or corrosive residues. There shall be no damaged parts that may adversely affect safe operation or mechanical strength of the equipment such as parts that are broken; bent; cut; or deteriorated by corrosion, chemical action, or overheating.

Not a good solution, but one that some people mistakenly take and think is okay.
Mostly because nobody is going to want to pay for the cost to demo the building install a new panel and fish all new home runs or deal with junction box covers all around the panel with splices.
Most buyers don't pay attention and they buy the large plasma TV or make a down payment on that new Bimmer ...

Re: White paint in electric panel ?
The code says that it is not allowed. Period.
I would take the cash and use it in another way too. That's at least 5k worth of work that is unnecessary.

Re: White paint in electric panel ?
I was cringing by some of the posts here, but thankfully others have responded about code and deleterious (sp?) effects.
I had to reject a new apt complex do to priming gone mad. Boy did the primer hit the fan over that one but I stood my ground.
I don't think any of the enclosures were replaced, just completely cleaned and the entire interior replaced as far as I could tell.
I have also rejected painted interiors of switch boxes and wires. A little overspray is usual.
Note that some old panels did not have buss termination requirements, but they were fuse panels of old. The termination requirements will almost always be in the enclosure where one cannot see the forest for the wires.

At the risk of taking this thread in a different direction (but it is done constantly), your use of the word "rejected" raised my eyebrows. How would you word your report concerning this panel box?

Almost looks like they replaced the breakers already because the the handles would be covered and almost impossible to clean.

Re: White paint in electric panel ?
I feel the same as Markus does on this. I seen a panel with a little over spray yesterday. As there was no over spray of the electrical parts (just cabinet interior) I let it go.
This panel obviously has too much.
However there is another area no one is mentioning. As the painting crew removed the cover to get a good paint finish around the panel, did they also remove every electrical outlet and switch cover in the building? Bet they over sprayed every recept and switch in the place.
