Start here for your wiring and breaker sizes http://crossy.co.uk/...it%20types.html don't try to continue to use AWG sizes, they will just confuse your sparks

It's common these days for the ground conductor in 3-core to be smaller, saves copper. If you can't get 3 core in the size you want just use regular 2 core and add a separate (green) ground wire, if you're running in conduit (advisable) then there is no problem (the single insulated wires should not be run unprotected).

Big name brands produce decent hardware (I like Panasonic) but there are others. I've had good results with Haco outlets, a modular system that allows you to choose the combination outlet styles you want, see them in HomePro.

Thanks Crossy for the help.

I would like to conceal my wiring in the wall but do not trust sparkys ability to do a good job. The only option that I see is to use conduit to carry the wires. I did this in my cabinet shop because it was considered commercial. I will probably use the plastic conduit and paint to match the room.

Thanks again for all the help you so freely give to the members here on TV.

We aim to please

Bury your conduit in the interior cement (Thais put so much you don't need to chase) not like the plaster we use in Europe. Junction boxes in the roof space with screw terminals or wire-nuts will keep it all safe and secure (take their roll of tape off them).

Naked cables / wires invite the local fauna to sample

BBT. The 3 core wire you saw was likely 2.5 x 2.5 x 1.5 & it's perfect for sockets.

For lights you can buy 1 roll each 1.5 mm2 red & black & use this for lights. Only the live (red) run to the switches, the neutrals can be "ganged" together anyplace convienient.

Part of the problem (among many) are the dam_n welding companies just sticking wires in the service point instead of properly wiring a temporary service outlet to use.

I think it's okay, except the earthing problem should be fixed. And love to see the wiring under the ground, instead of spaghetti like above the ground , like in Bangkok for instance. But that may take some time.

The poll results are expected but nonetheless interesting (although certain members have railed against this. i.e. claimed that Thai electricians are as good as any other electricians).
The poll began on the 30th of March 2007. Comments have included negative aspects of foreign (non Thai) electrical companies in Thailand.

The results may suggest that certain foreign companies, the origin of which (country) seemed to attract customers, was not "up to scratch".

In my opinion, this suggests that certain people (companies) have simply tried to "cash in" on the poor situation of Thai electrics without actually looking at;

1] country location.
2] general local installation techniques.

The result is, for example, a German person seeking an electrician who can wire the house according to the German (European) wiring code. This could also apply to an American, wishing to have American style wiring in the abode. These requirements seem to be easily (sadly) fulfilled.

The end result is a mish-mash of wiring that not only confuses the existing electrical situation in Thailand but also creates potential disasters.

There is only one way for Thailand to electrically progress...and that is to adopt a relevant set of standards. The standards of cold countries do not apply here even though the standards may appear to do so.

Thankfully, the education of Thai "tradesmen" (for the want of a better word), is slowly changing toward a more "apprenticeship" style system, although I believe it will be many years before "Thai culture" will not interfere with the approach toward a technical situation.

Thanks to all who participated in the poll .

I agree 100% with what elkangorito says above.

As I've noted in other threads, rather than using inappropriate standards, or worse, parts of inappropiate standards (such as using UK style ring-mains without the use of fused plugs). We should concentrate on improving the QUALITY of the installations by encouraging the use of proper connection techniques (wire-nuts), a uniform colour code and proper cable containment / protection and not running unprotected single wires.

I am not aware of a Thai domestic installation standard (although there is a PEA guide). In the absence of suitable documents I suggest we utilise the Australian standard as a basis, it has been developed for a similar climate.

This poll has now run its course, so I'll close the thread (with the agreement of the OP). We have several other electrical threads running and any member is welcome to start new ones.

Stupid questions are welcomed, we would all rather answer 'stupid' questions than read of some young life lost because a question wasn't asked.
