Can you spot the Code violations?
Hint: Think protection
How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. Joe Tedesco, who has a knack for finding shoddy electrical work, did the dirty work and found this mess. Now it's your turn to identify the violation.
Dylan McLaughlin submitted these comments. “It's hard to tell from the picture, but it looks like the ground wire is just kind of leaning on the back of the panelboard and is not properly attached. There's a transformer hanging, which is putting pressure on the wire connections. It also looks like there are wires twisted together without the use of twist-on connectors.”
Jim Malik, an electrical controls engineer for RPI, Inc. in Racine, Wis., says, “This is the worst enclosure I have ever seen.” Malik noted the following problems: wires crossing terminals; wire must run point to point without splices; device not mechanically attached; E-stop not easily accessible by operator (probably no E-stop legend); not a wire label in sight; and who knows about wire size, colors, etc. He concludes by saying, “I can't believe this is real!”
The bottom line is this mess is a clear violation of Art. 409, Industrial Control Panels.
