Looks to me like a plumber had a lot to do with that mess to begin with. More plumbing fittings used than anything else.

Trumpy, NO we are not required to place warning signs for cable exit locations. Something tells me that if we did, they still wouldn't be placed at that location!

Mid-span taps are done here all the time, but they are usually very short and are slack spans to avoid placing any tension on the main span. It's very common in dense urban areas.

EV,
I never knew that, over here any overhead service line has to be attached to a pole cross-arm, via an insulator.
At least if something does catch the service line, the insulator will usually break, but the insulator bracket will take the force and hold the service line screening to prevent the Phase wire of the service being torn out of the fuse-holder on the pole cross-arm.

Yup. In sections of Queens, Brooklyn, Bronx & Staten Island; that's also the case.

Manhattan is the only section of New York City where you won't find any overhead wires. By law.

Part of the reason why they're constantly ripping up streets to replace cables (and also why you get electrified manhole covers after snow-storms).

Mike,

Here in the US, most if not all small overhead drops don't have any isolating fuses. Does every residential service have individual fuses?

Mike that IS a power cable!!! the conductors are run in black ABS, which is used over here for wase pipe.

But Mr. Inspector, it works.

They call those mid-span taps "bridle's" over here (At least in LADWP territory, they have 'em all over in their older areas) So Cal Edison and SDG&E do as well, but not nearly as many as LA...

Larry, I believe in NZ they do fuse each resi service separately, likely to keep potential fault currents on the downlow (my guess at least )

Trumpy, that's not a midspan tap, if you look closely it's just one set of triplex guyed to another pole, this was done to allow the serice to clear the house, our local POCO does have midspan taps, but they're rare, and only in the older areas

No that's cool, it just looked a little wierd when I first looked at it.

Yes, Randy (Lostazhell), is correct we have always individually fused houses (and most other things here too).
The high fault currents caused by the Multiple Earthed Neutral system here require that an individual installation (where a fault has occured) be disconnected from the supply without affecting other consumers on the same lines.
One other very good reason for this fusing system is so that electricity companies can easily disconnect houses where the person in the house has defaulted on their electricity account, it means that you can pull the one pole fuse and be sure you've got the right house (sometimes).
