Thanks Brian! I get a bit worried about long underground conductors and like to have the comfort of mind to have them tested prior to flipping on the switch.
at first i thought that conductors are normal sized and ladder and room is extra small, but then i slowly started realizing that those are arm sized...
There might be a reason to perform the test that way, I can’t recall now if I did any like that. The purpose of the test is to determine whether the insulation is damaged and in an environment that would allow current leakage. So if I grounded one end, I would not be able to determine if there was a “leak”. Because it would already be shorted. If that makes sense.
@@sircampbell1249 Haha yeah, these pulls were 1080' long, we had a lube pump on the feed end. Not sure how many gallons made it into the pipe, but it was a lot.www.polywater.com/en/product/polywater-nn-lubricant/
@@TheElectriciansGuild All that damage to those conductor sleeving, meanwhile we see standards elsewhere lugging massive 3 or 4 conductor armoured cables without issue. In north america that steel conduit always rots out with rust in outdoor salt settings... the standards in North America don't appear to cause less electrical fires either, only cost significantly more money?
I have never heard of anything like that. That was cool!

BEEBBEEEBBEEEB.....!!!!

Haha, they are about 3/4” in diameter.
Is the ground suppose to be connected on the end of the cable without the leads, so basically is one end of the ground cable landed ?

I’m the 40 th sub!
Congratulations! Thank you for joining the channel!
What is the difference between these cheaper insulation meters and a megger? Just the sensitivity?
This is a megger.
All phase conductors that are not being tested should be grounded during the testing.
Would this be a safety precaution?
That cable doesn't look good..
The last 4’ did get scraped coming out of the connector during the pull. They did test out though so it’s all good :)
