What's the rule on service/house drops. It was always my understanding that it was a "do not touch,do not grab" policy. Ineed help w/ this one ASAP.
Thanks

We're down here in La. Funny you are the first to reply. The USACE has Hard and Fast Rules, 10', no exceptions. It's killing us and slowing down production.
The osha standard says that only a lice clearance tree trimmer can approach closer that 10 ft to any electrical conductor.
Most clearances that utilities require are arouns 3 ft around for tri-plex line, open secondaries may be more.

qualified line clearance: avoid contact
other than line clearance qualified: min 10 ft.

You guys making any money down there?

Qualified - avoid contact up to 1Kv (gradual increases thereafter)
Non-Qualified - Min 10 ft up to 50kv (gradual increases thereafter)
10 ft seems a bit far for non-qualified on house drops but I guess it covers a lot of different skill levels?

as far as I know here its 3M (10ft) from any energized conductor unless qualified. although routinely ignored.
the last fun one I saw was two grass mower guys trimming a laurel hedge that had a house drop going near it. they tied a loop in a nylon rope, lassooed the house drop and one guy was holding the tail of the rope and pulling the house drop out of the way for the guy with the hedge trimmers. yikes.

b) At least the following clearances, as set out in the following table, are maintained between the worker or the equipment and the overhead power line conductors:

I was working in a big switchyard recently with 500KV coming in. Anyone want to dance with that? 7 meters sound reasonable to me; but I'd keep further if I could.
PNG rocks for stuff like those attachments!

Wierd hey, check this out.
Uncertified must keep 3m (10') from service drop.
Certified must keep 1m (3') from service drop.
Yet, I assure you, that many many houses when you walk around them you are well within 3' of a service drop.
If the wire is in contact with vegetation then you are not supposed to touch that vegetation (or wire).
Booking in for a service wire drop around these parts is unbelievable, and private electricians don't wanna know about it either.
To go by the book we're to book the energy company to clear the wire then we can work on the tree ... it's a real PITA area with lots of improvision going on. /forum/images/graemlins/shakinghead.gif
And then if you think I'll just get some rope or use an insulated pole etc to pull that service drop out of the way ... hmmm, wrong. The pole etc is supposed to be tested and tagged every 3 months! No tag, no go. So, using your plastic rake or your pole saw handle is a no no, let alone pulling the service wire outta the way with ya throwline or some rope.

Home service wires are usually under the radar or less than 750 volts phase to phase.

Kevin from that table it says to keep 300mm away, about 12". Aound here if you are certifed we just can't touch it. We have put many clean and dry ropes over the service drops to pull them out of the way.

I've only encountered one service wire that was rubbed through to the bare conductor but due to neglect of clearing the trees I'm sure there are many more in my area.

I too have seen bare copper on a service drop after finding it with the lift, gave me a little scare. Managed to catch some of it on tape /forum/images/graemlins/grin.gif.

Kevin:
HOW DARE YOU SAY SOMETHING LIKE THAT? Our lines aren't overgrown...they just haven't been touched in 25 years /forum/images/graemlins/grin.gif Its why I have a job now and most of our work gets done during an outage.
I've come across 3 service drops in the last year that had worn through because a limb or base of the tree was rubbing against it.
Triplex service wires are pretty safe for the most part. My suggestion would be not to reach out and grab it but prune it first. We sometime throw a dry rope over the wires to pull it away from the drop zone but we're also the power company. If we mess up a service line no big deal.. justa bunch of paperwork.
What you should be really looking out for is open wire secondary. Its an older type of house drop, I've only seen it 6 or seven times but that was in my previous life in Detroit.
There's enough amperage in house drops to kill you many times over, just keep that in mind.
