New house supply, Bangkok

Postby ratsima » Wed Jun 03, 2015 9:32 am

The elctrician comes next week to finish the installation, part of which is connecting the house to the public supply. This is where I would really like some advice please. There are a number of options and i am caught between them. There are probably more options that I haven't even noticed! :)

Please have a look at the graphic.
Elect Supply options.png

Existing situation is as follows:
A-F Temporary cable slung from Main strret supply pole to temp 6m steel pole on the plot edge. From there the builder cables up as necessary.

Plans
The new indoor electrical distribution panel will be located at E, on the kitchen wall adjacent to the outside wall. The boundary wall runs only 50cm from the house wall on this side of the house (the other side has 70cm)

Options
1 run supply cable as at present, A-F, then underground to E. Problems: underground channel would be circuitous as beneath the house is already concreted. Cabling would be inaccessible. House is raised above ground so it would be a very wet area probably.
2 erect new pole at D and sling supply cables from A-D. Problems: neighbour has trees on that side of the wall (B-C-D) and there would be maintenance work forever to keep the trees clear of the cables and potentially problematic as the neighbour owns the trees. Also, maybe 23m+ is too long for a single run of cable and another pole needed in the middle?
3 dig up the recently laid water pipe trench from A-WM. The street surface is already damaged by the installation of the water pipe. Install electrical piping beside the water pipe. From WM, cable can run along the inside of the wall B-C-D using steel conduit (square or pipe), then elevated to go across from D to E. Or, from WM, cable can go underground to E (no concrete yet at the sides of the house). Problems: lots of work, maybe not to code, cable inaccessible.

There are variations among these 3 main options. Option 2 seems to be the least-worst option but any advice would be gratefully received.

Whatever option is selected, is there anything I should be watching out for in terms of how the work should be done? For example, can I use a metal pole? If a metal pole is used, does that require special earthing? We have used the same electrician for many years but whereas he is understanding and quite modern thinking, his team can be lazy and prone to the worst short-cuts and shoddy work.

A general question, is there any piece of kit that could make the supply installation and the house installation be tested more easily? I have small hand held AVO type tools but maybe there is an electrician's level tool that can check and would be worth the expense of buying?

Thanks for any advice, it is much appreciated.

Hello Ratsima,

I'd go from A to the front of the house (somewhere near point C on your plan).
From there, go under the roof of your house and over the ceiling if that's possible.
Or run it along the wall, high up under the eaves.
Putting up poles next to your house with so little space will very likely not be approved by the Electricity Company.
There's a minimum required distance from the neighbour's land I think..
(I could be wrong, but I base that on a situation I had some years ago where we wanted to put a power-pole along the fence of my factory. This was refuted as it's not allowed by law. Minimum distance had to be 2 meters, so we had to abandon that and put a pole right in front of our Company Name and Logo...)

Also, up till your house, you'll need the more expensive cable for outside use.
After that, if under the roof, you can go with lower spec cable if you want.

Good luck with it.

I had to put a concrete pole in otherwise my cables would have run over the neighbour's land right in one corner. It was quick and painless, the truck arrived with the pole and they used the crane to lift it and drive it into the ground right in the corner of the property. The total cost was 8,000 baht which included the running the copper cable to the house (using the slack I had in the cable) and they were done and gone in 30 minutes, which included the seal of approval from EGAT.
Be careful about digging up roads, you never know what you'll find.
I'd ask the people from EGAT to tell you the best option, they can also check the supply (and they will) in the house to make sure it is connected properly. They have all the meters in their truck and they are quite professional and you will need their stamp of approval anyway.
As far as I know, metal poles are forbidden. Even with two poles and them running the supply you should get out of it for under 20,000 and that's with the approval to permanently connect.
I would seriously think about changing your meter at the same time to off peak. For the 1,000 odd baht it pays for itself after a couple of months.
Good luck.

Made on December 14 2017 because there's nothing like keeping a thread up to date if people are reading it. I thought that was the object of a building blog, but I may be wrong.

Not wrong at all, however I think that the poster "Hermonar" is probably not a legitimate user given the 2 rather strange posts.

I could, of course, be totally wrong, and he/she could be a welcome new addition. If that is the case then I offer an apology for my suspicions.
There was no spam in either of the posts so I've done nothing. It looks as if the poster is not to far from you according to the IP address, though that could be spoofed.

Personally I am coming out of Tokyo, Japan at this hour, so I wouldn't put too much faith in I.P. addresses. The hour before out of Singapore, I use AVG Secure Pin and have it set to change every so often. It costs money but it makes it safe from prying eyes.
The only ones that show the real IP addresses are spammers from Pakistan and sometimes India, the rest are all a lot smarter than that.
