Thanks. That story came to be because of this story.

I'd been in the trades a few years when we were working on a house on the beach in Malibu.The service came up on the side of the garage to a pull box and then continued to the main service panel at the rear of the house. I was doing the hook up at the pull box. I had already striped the first POCO conductor and was working on the second one when I heard a pop and saw a little puff of smoke. I looked down and the whole end of my knife was gone blade and all. As I climbed down the later feeling a little confused, my boss and my brother both came running around the garage screaming wanting to know if I was alright. I said yeah and told them it was no big deal and what I had seen and heard. My boss said, boy that "pop" sounded like a cannon going off and a huge cloud of smoke came billowing over the garage. My brother agreed with him and said they were sure that they were going to find me dead. Turns out that it was lead coated conductors and somehow I had striped the first one with out touching the lead and the copper at the same time of course not so luck on the second one.

The guy I was working with the day of the cement truck knew that story too and when that chute dropped he about jumped out of his pants too. Like I said funny afterwards but we almost had to give each other CPR.

I will add this to my general posts on electrical safety.
I perform mostly inspections and consulting when on jobsites these days. I also perform safety procedures. I have the PPE and the training to know what I can and cannot do. I may not perform it perfectly, but I am a lot, repeat, a lot safer in my work habits than I have been in the past.

As am I. I sometimes wonder how I made it into my thirties with the way I did things back then.:)

Wow, confused on this part though.

The POCO used a lead coated wire because of the salt air, so I was told. So basically you had, in reverse order, the copper wire, a thin layer of rubber, the lead shield, and then the outer insulation.

On the first conductor I knew I was having trouble, but I was being careful and I guess my knife didn't cut through the thin layer of rubber. On the second one I got a little more aggresive and "pop".

At the transformer the lead is grounded, I believe. I had never seen it before and to tell you the truth I have never seen it since.

OK, I'll try this.

Has anyone who has installed residential over head service upgrades contacted the local power company and have them disconnect the supply power? If so, how were the results?

Thanks,

Michael
This is not allowed in our area, if you do dissconnect you will be assessed a fine.

There is problem with scheduling as the Power company will not give exact times for disconnect and reconnection.

No, not really

Even with the proper PPE an electrician can only work hot for troubleshooting or when shutting down creates a bigger hazard.

PPE does not allow us to do anything we want.

right tools for the job

right tools for the job

I have been working residential meter pan and fuse panel/breaker replacement for years now and I have always considered it safe as long as I had and used the proper equipment/tools for the job. Its one part of the job you want to take your time on and not rush.When I first started doing electrical work years ago I always like to watch and talk to the electrical utility personel on the hook up and connection of the service it was always something interesting to watch.An old timer named 'BUDDY' (ENTERGY)- NEW ORLEANS) always gave me some pointers on the live working of secondary drops and still remember him today..Investing in the proper tools is a must to do the job right and safe.
1.PROPER LADDERS ARE A MUST
2.GLOVES AND SLEEVES
3.INSULATED 1000 VOLT TOOLS SOCKET SETS,HEX BITS RATCHETS.SCREWDRIVERS
4.BURNDY H TAPS THE BEST WIDE RANGE AND CHEAP
5.BURNDY MD-6 CRIMP TOOL W BRUSH GUARDS ECONOMICAL AND EASY TO USE, GREAT CONNECTION
6.2 1/2 INCH 3-M BLACK TAPE
7. PROPER VOLTAGE TESTER

Did one Thursday. Cut and tape the overhead, demo and rebuild the service, reconnect the overhead, collect the money, call for inspection. :)

On the rare occasion that I called poco, they will disconnect from the transformer, but no specific time. :mad:

I have done probably 100 service upgrades in my career, many uninspected (in the olden days).

EVERYTHING now days is inspected by both the cities (major metro area, Phx AZand surrounding areas) and POCO's (2).

In MY opinion it is not that dangerous if basic guidelines are followed and the POCO installatiion is safe and secure. You are just cutting a wire and reinsulating it...right? Just focus and don't do anything stupid.

That being said there are a lot of smart people out there who have done stupid things.

POCO linemen are trained to deal with the service drops and should be the ones disconnecting and re connecting.

One main issue is the condition of the conductors. A LOT of times the are sun baked and split. You DON'T want that liabilty.

Another issue is the placement of the transformers. GENERALLY they are well above the low voltage service drops but occaisionally I will come across one that is below, causing a potentially SERIOUS accident if the triplex comes into contact with it (my one and only near death experience).

One more issue is what to do with the drop during the upgrade. In the olden days I would just lay them on the ground and hope that the installation at the pole was secure. The POCO's here tie them off to an AC unit, Vent stack, or what ever is handy and secure using mule tape. If they are replacing the drop, they remove it as part of the disconnect.

The down side of having POCO disconnect is that it puts a few more people into the loop. MOST of our upgrades are in occupied residences and need to be powered up the same day. It it a real struggle sometimes to get everything torn out and put back together in such a short time. Some of the problems we encounter are:

1. POCO shows up late (or not at all..whoops) The guys are there to do the work, the customer has planned his day around it and because of an error in the office, no one shows up. It happens all the time here.

2.POCO or city inspectotrs show up too EARLY and I'm half done. I have had them REFUSE to return. It happens all the time here.

3. City inspectors don't show up at ALL. They always say "I'm too busy". POCO won't reconnect without city clearance.

4. Paperwork gets lost. The city inspector calls his office who the FAX clearance to the POCO. Come on now, it's 2007. Who sends a FAX? The fax gets lost or the machine is out of paper or the person who is supposed to take the fax to the dispatcher has gone home to take her cat to the vet.

5. POCO doesn't come back to re connect. Shift changes here are at 2 PM. It's like a whole new world where no one talks to anyone else. The crew that disconnected are gone and they could not care less about the customer. Neither POCO has a decent system set up to deal with this. I have had customers without power SEVERAL times because of this. I have reconnected myself more than once.

6. POCO changes their regulations without notice OR explanation. What we have been doing for years is now unacceptable and has to be re done. Send out an email dammit! Cutler Hammer came out with a nice 200 amp resi all in one panel that would work for underground as well as overhead. All you had to do was relocate the jugs. Some genius at APS decides that this is a bad idea and bans them from their acceptible equipment list. We find out the hard way.

Bottom line is that POCO should disconnect and reconnect. It's a good time to inspect the drop. Just understand that it take HOURS to do the re installation and have someone available to inspect (and or replace) and reconnect the drop when they are done.

As far as guidelines, the obvious ones are :

1. Proper training to inspect drop.

2. Proper equipment ie correct ladder, gloves, tools and tape.

3. Properly secure the old drop if it is being re used.

I personally don't think I get paid enough to do live service changes.. Someone mentioned the owner of the company doing it. I like that idea! LOL!

Possibly true. Oddly, this is right from one POCO's rules book:

A licensed electrical contractor who is upgrading or performing maintenance on a single-phase overhead service of 200 amps or less, and not changing the point of attachment, will be required to disconnect and reconnect to the Company’s service drop, unless a two wire service drop is involved or other unusual circumstances exist. The connection must be made with permanent connectors. The Company recommends that all connections to the service drop, by the contractor, be made with compression connectors. Appropriate and properly applied mechanical connectors are also considered permanent.

I've noticed that customer service from the poco is almost non-existent these days, at least when it comes to this stuff. Particularly when a large company from England comes and buys all the local poco's and the gas company. :rolleyes:

I know that cuting a service loose and reconnecting,can be done safely.
Most of us have done it. (service electricians):

Sure most of us have done it.

Regarless it is an OSHA violtion for us to 'do it hot' and we should start trying to change our mind set on this.

I might as well post this from OSHA here as well

1910.333(a)(1)

"Deenergized parts." Live parts to which an employee may be exposed shall be deenergized before the employee works on or near them, unless the employer can demonstrate that deenergizing introduces additional or increased hazards or is infeasible due to equipment design or operational limitations. Live parts that operate at less than 50 volts to ground need not be deenergized if there will be no increased exposure to electrical burns or to explosion due to electric arcs.


Note 1: Examples of increased or additional hazards include interruption of life support equipment, deactivation of emergency alarm systems, shutdown of hazardous location ventilation equipment, or removal of illumination for an area.


Note 2: Examples of work that may be performed on or near energized circuit parts because of infeasibility due to equipment design or operational limitations include testing of electric circuits that can only be performed with the circuit energized and work on circuits that form an integral part of a continuous industrial process in a chemical plant that would otherwise need to be completely shut down in order to permit work on one circuit or piece of equipment.


Note 3: Work on or near deenergized parts is covered by paragraph (b) of this section.

I don't know about you, but the fact that I can't get the POCO out to D&R in a timely manner qualifies as "operational limitations" to me...
