Auber Enclosure Grounding Post

[butterblum]

Just tried to tighten a locking nut on the door ground post for my Auber enclosure, and it snapped clean off. It just had a single tiny tack weld holding it to the door....
I am just using two switches, a buzzer, and an EZBoil on the door. I measured 0.2 ohms resistance between the bare spot on the door and a bare spot on the enclosure. The hinge is the connection.
Do I need to worry about grounding the door? The switches and buzzer are plastic, so the only way the door is getting energized is if a wire comes loose.
I really don't want to drill a screw through the door for aesthetic purposes.

Can you solder it back in place, or pin the ground wire under one of the switches to the door or something? Probably won't be a problem if not. But the fact there is any resistance (assuming your ohm meter is calibrated) indicates a ground strap would be in order.

I drilled into the bottom lip of the door and used a screw with a locknut. Works fine, and doesn't look too bad, but it makes me question the strength of the welds on the grounding posts inside the enclosure now.

Enclosure doors usually are grounded through the pivot pin or hinge anyways. Electrical code dictates the ground strap so as to be absolutly sure its firmly grounded.

you dont need to tighten them much.. honstly there should be star washers that crimp down as you tighten the connection so there shouldnt be much stress on the post. I wouldnt stress too much about meeting code on this one.. if you were building to code many inspectors require you to replace the ssr and contactors that auber sells with UL listed components anyway which is something I just had to do on my panel.

For me, it's not about meeting code. It's moreso about doing everything I can to maintain peace of mind in regards to safety.

Understood, But ironically thats supposed to be the goal of the "code" ideally... That is why it exists anyway despite how and why its being enforced now..

Right. Understood.
