What can you find wrong here?

Recent rewiring job in Orlando, Florida

It looks like the corroded box is outside or has been (or is) in a wet location...no cover. Furthermore, it probably isn't grounded, although it's hard to tell from the picture. What immediately jumps out at me though, is the single conductor (besides the ground) emerging from the left-most conduit. A real no no.

On closer examination of the picture, I DO see an additional black wire ....so nevermind about the single conductor.

This junction box was in a damp location that was actually about 75 feet away from the open area outside. It was located near the pool, and the hot humid weather in Florida could have added to the misery and corrosion here.

Joe,

In NJ the electrical inspector has to look at every public pool each years for visable violations before a pool can open. Plus the public pool needs a pool bonding and grounding inspection certificate that is good for 5 years. If the public pool does not get them than they can not open up their pools for that year.

Harold,

What kind of testing is done to validate the bonding? I mean, what is the procedure, do you know?

This is horrible, I've seen this many times. I used to work at a car wash and all the boxes were so rusted and the outlets were rusted to. The whole wash was always wet inside, and only one outlet was GFCI protected. It was sad.

Hello, I am new to the fourm but visit it often. Besides the box being rusty another problem is the way they tied all the neutrals together on those multi-wire circuits.

I always get confused when I see all of the neutrals under one wirenut. It appears there are multiple circuits.

Bill,

In NJ you have to get a bonding and grounding test done every five years. The contractor who does this has a special meter that has to be checked by the state for accuracy. He then will test from point to point to measue an resisitence of 25 ohms or less. ( I believe.) Then he will issue a certificate. I as an inspector just have to do a visual once a year. I look to see that all pool equipment looks in good shape. ( No loose connectors or bonding wires, new motors etc.)

Harold,

You're talking about Public/Commercial Pools, Right?
Or do private, residential pools have to be tested periodically too?

Bill

do I see 3 or 4 circuits being fed by only 2 neutrals that are tied together?

Also, isn't that box a bit too overcrowded?

Bill,

Sorry about not getting back. I forget where all my posts are. In NJ only the public pools get inspected visually once a year and the bonding/grounding test is given every 5 years.

Harold

The enclosure’s chain indicates that it probably is the remains of a NEMA 12/13-enclosure, a/k/a “JIC” [Joint Industry Conference] can—a far cry from a NEMA 4X rating for the corrosive conditions. Sickening at any rate, and surely a misapplication the instant it left the supply-house counter.
