Do you think that a Home Inspector should be able to identify the following items to make sure that they were used or are being used correctly?

I have noticed a few of the images posted here that seem to have the improper fitting used at a panel, such as a "Romex" connector used for the termination of "BX" cable, etc.

I believe that this will be a good subject for us to discuss here.

I plan on trying to give the items a picture unless someone with more time can help to locate them? Hint?? John? or ???

Thank You Joe! That’s exactly what I wanted to find. I have asked them in the past for help and they sent me a CD with the images.


Here's an example of a good question to ask a HI:



Question:

What is this fitting used for, and why is there a small oval hole in the clamp cover near the two support screws?

Good topic Joe,


I know it was just an example but your pic is for armored cable and I have no idea what the hole is for. .

I believe the hole is to see the anti-short bushing and to be sure the cable is fully inserted.

LOL… Look what this guy did with one of those fittings:




Also, they're in serious need of a bender...

Bingo!


ARTICLE 320 Armored Cable: Type AC
Quote:
320.40 Boxes and Fittings.
At all points where the armor of AC cable terminates, a fitting shall be provided to protect wires from abrasion, unless the design of the outlet boxes or fittings is such as to afford equivalent protection, and, in addition, an insulating bushing or its equivalent protection shall be provided between the conductors and the armor. The connector or clamp by which the Type AC cable is fastened to boxes or cabinets shall be of such design that the insulating bushing or its equivalent will be visible for inspection. Where change is made from Type AC cable to other cable or raceway wiring methods, a box, fitting, or conduit body shall be installed at junction points as required in 300.15.
