Electrical and services wire channel system

Postby groucho » Tue Mar 19, 2013 11:32 am

Hello,

Recently I saw a great photo presentation, I believe from Dozer. It showed a electrical channel/trench suspended from the ceiling rafters along the interior walls. The channel provided a causeway for attaching individual conduits that dropped down through the walls. I want to show these photos to my contractor and electrician, as I will be rewiring my house in Bangkok. For the life of me I cannot find the photos. Could someone please point me to the link.

Many thanks,

-O

To my knowledge my build was the only one using trunking and I posted a couple of pictures somewhere on one of the topics some time back. The electrician I used is wiring my friends place and he is using the trunking after finding out how much better it is for wiring in large houses.[*] :lol:

Thanks pattayapope, very nice plan. Although the photo's (several) I saw were presented as a series. I am still digging around, but cannot find them? I hope someone can redirect me.

pklongball has done an excellent job showing pictures of wireway trays in his electrical photo gallery. His complete gallery should be a must for anyone thinking of building.

Take a look @

PVC trunking is actually available everywhere and is cheap. White costs slightly more than grey. The problem is training the average electrician to use it. Most don't even put the wires in the roof space into neat yellow conduit. Junction boxes have neever been heard of, and insulating tape, yards of it, rules the day.

Why not introduce them to push-fit connectors? (sometimes called cage-clamps).

Why complicate things twist-on wire connectors or wire nuts are easy available and have been used for a long time without problems.

Just make sure to wrap the wire nut and wires together with electricians tape when done to ensure that the plastic part never departs the metal spiral leaving an exposed connection. It does happen if no tape is used.

The push-on connectors avoid all these problems and are nowadays a standard European method. Admittedly they are more expensive than the twist-on caps, but again, their use will not impact on the cost of a total project. Once introduced to them, Thai electricians are seduced by the candy colours and won't go back to the old way. There are several brands of these push-in connectors but they all look basically the same. They are available in Thailand but I don't know of any stores that stock them in Pattaya/Jomtien - if indeed most electrical retail outlets in the country have ever heard of them. I've generally only seen them used here by Western electricians.

The push connectors are available at the electrical shop on Theprasit road, if you drive down from Sukumvit just after you pass the MP garage look to your left and you will see an electrical shop with various types of fans outside. The owner speaks very good English and is helpfull and I have done a lot of business with him and his prices are very fair. They come in 3, 4 and 5 way and are about 4 to 6 baht each from memory.[*] :roll:

Ah, I happen to know who distributes ( or who has been distributing) those . As far as I know, however, they are only available in the Pattaya area.
