ECN Forum Forums General Topics of the Trade General Discussion Area Inspector's Exam

Boy I am mixed up....
I think it's the terminology.

We need more pictures.

'66,

You cannot link to the page. If you can copy the question and paste it here We can disect it. Or, tell me what it was about and I will find it.

66',

A bonding locknut does have a set screw that is pointed & will dig into the sheet metal. The screw must make up outside any pryout rings & this usually means all of the rings must be removed.

I thought I told you to read all the questions carefully. If I didn't, sorry 'bout that.

You should have heard all the screams early in the inspection program when we told folks they'd have to take apart their work & install the ground bushing.

Good luck on your test. Where are you going for it, Charleston?

is this is?

OK, that's what I had originally pictured... but I had assumed that the screw was to terminate a bonding jumper... not a "bond screw" per se...

So I'm back to being correct on my call to the AHJ...Whew! That's good!


A picture is worth a thousand words!

Good work! And I see that they call it "grounding" rather than "bonding".

Locknut (note: no lug):



Bushing (has jumper lug):

Bill,

Here's the question in question (that sounded funny...) from Mike's Coe Quiz...

Emphasis is mine for clarity...

2. 6. Service equipment, service raceways, and service conductor enclosures shall be bonded by ____________.

A. threaded raceways into enclosures, couplings, hubs, conduit bodies, etc

B. bonding-type locknuts can be used on raceway or connector terminations where concentric or eccentric knockouts are not encountered

C. service metal enclosures, raceways and cables can be bonded to the grounded (neutral) service conductor

D. all of these


I wasn't saying that the question was in error, it was worded to help support my own assumptions in my own mind, or something like that...

I think I'm clear on all this now...

Thanks once again guys...

I think Steve said in another post that ECN should count as CEU's... I'm in total agreement there!

A set screw would probably push out the "pryouts".

Standard locknut:

Tom,
Yeah, I'm hoping in Charleston, Mo'town is quite a ways further...

Sylvan Tech is closed until Monday, so I don't know if/when they're giving the test yet...

I think I can lick the 1st one, but the general looks like a tuffy!

Found out today that the local AHJ is trying to handle the tri-county area alone!
There's plenty of room for "competition"...

Thanks Dspark, the pics have helped immensely.
