This thread is inspired by the horrific overhead wiring photos posted on the Human Powered Generator thread - I won't derail that thread any further.
Don't know why, but I find dodgy overhead wiring appalling yet fascinating at the same time. These photos aren't in the same horror category, but are interesting all the same. Taken about 6 months ago, first one is in Phnom Penh, note the open junction box, next 2 are in Hanoi, both systems are 240V.

I'd say the risk from the wiring is minuscule compared to the chaos going on in the street below.

What's that power pole in the first picture made of? Looks like four pipes welded together. Don't they have trees in that part of the world?

I would say the pole in the first picture is made of concrete.

You should see the extension cords coming off nearby poles in cities like New Delhi, the majority cannot afford an electric bill, so you slip the local service supply electrician a few rupees and your in business, it makes the poles in the photo look pristine!

In both photos many of the lower lines will be telephone cables. If you want to see bad electrical wiring, you need go no further than Mexico.

When I was in Cuba many years ago, the shower water was heated by a bare coil in the water flow. If you got too close to the shower head, you got a shock.
We developed a procedure:
Water on.
Heater on by 2nd person standing on chair.
Shower while squatting.
Heater off.
Water off.
If you turned on the heater without water flow it burned out almost immediately.

The very first steam cleaner we bought was an all electric one and we had to have a new supply cable laid in for it.

Can't remember the name but it was a very heavy professionally built unit by a well known maker.

I consisted of a large steel vessel with a cover plate on top about 3/4" thick held to the vessel with about twenty 3/4" bolts, in this top were three 1/2" steel rods passing thru insulated bushes, at the end of these rods were plates about 6" square welded to each.

Three wires went to each of the three rods and these went thru a large contactor direct onto the 3 phase 440v mains. In use a donkey pump driven by a small motor fed water into the vessel and when it reached a level switch the contactor came on and 440 volt three phase at about 200 amps per phase passed into the water which turned to steam.

It worked well and no one got a shock off it but we replaced it with a diesel model because one day we smelt something burning and all the pitch was running off the incoming mains cable where it went into the Electric boards fuse box. :eek:
