No on is discussing SAFETY while working inside the “Limited Approach Boundary”. What I see in the video is troubleshooting without the proper PPE. Regular work gloves don’t provide protection from electrical shock. This leads me to question if the electrician has been trained appropriately as required by OSHA 1910.332(b)(3). Please be a good example for those watching that might not have a full understanding of the risk and consequences associated with electrician work. Thank you

Lol same here. I have a feeling they will need it. However, we didn't leave the extra fuse on site. We now stock one in the van...they will call again. Thing is massively overloaded.
We check for blown fuses with the disconnect energized. I know that we are required to wear proper PPE so we glove up and mask up and check from top to bottom across the phases. Have you ever ran across a " Ghost Fuse "?......I have ran across 2 or maybe 3 in over 40 years of troubleshooting. We are looking forward to the result of this service call.
Why did they have to kill power to test the fuse? They already checked voltage in the line side of the disconnect (that they kept referring to as the primary as if it was a transformer?) they could have just checked the load side of the fuse for voltage… I’m all for safety and energizing whenever possible, but they already violated the arc flash boundary without proper PPE to take the voltage measurements.
Had to kill the power to replace the fuse and further test for shorts. They found some the place overloaded. Each leg was hitting max amprege with each unit having strip heat. Ended up a dryer was faulty causing the short. Non the less a 9k estimate was left with a warning about the issues and the hazard it is causing. Ask me if they approved... As far as PPE, not sure what type of electrician you are but on 120/208 if you suiting up, to measure across a fuse or line to ground, I give you props. 🙏 Arch flash is REAL always be safe.
@@The360Electrician ah, I see. It sounded in the video like you were saying that you couldn’t test the fuse without securing power. And I’m an industrial electrician, I was just sharing what the rules “technically” are per the NEC, but only because I didn’t know where they were going with needing to shut down the panel to check the fuse…
@@persona250 Great question. Anyone that has been on the field knows that sometimes the individual breaker will trip slower then say a main breaker or fuse. That's what we believe was happening on the in rush power of the motor. The individual breaker was sized correct but the other loads added to the main fuse were already close to its protection rating. Soon as the bad / old machine was kicking in the overload went to the fuse not the branch circuit breaker.
Exactly! They just assumed that a fuse was blown without checking, said they’d go get a fuse and come back? They should have checked voltage across the fuse to verify it was blown, then take some measurements on the load side of the fuse to see if there was a ground on that bus. That way they’ve got an easy dummy check to say the fuse (probably) won’t blow as soon as you swap it.
No ended up that the entire system is already overloaded. It was a bad dryer putting it over the top. We gave a 9k bid that included new load calls and upgraded panel. We also told them we would do an inferred scan and report to show them the hotspots.....still waiting for approval

Safety first!

@@Texelectric Well said, we all tend to preach to the choir, we all know the risks and should take them seriously.
I've had a similar situation last year and convinced the customer to purchase two extra fuses.

@@The360Electrician why would a short on a dryer blow the main fuse ? Surely there is a couple of breakers In between.

I wonder how it will go for you. Was there a short circuit causing this, an old fuse going bad, or overloads leading to this? Strange.

Loving these field videos, Jeff!
Thank Stephan, means a lot coming from the master himself. I just spent about 2k equipping all my techs with cameras. Let's see where it goes!
