Circuit breaker advice ,

Recommended Posts

I want to bring power  to a Sala I have build near one of the Electric feed poles in my property  ,  only enough for a light, and an outlet.

The sala is to the right and a few feet behind the Picture of the pole.

This picture is from before I put the electric pole.

Anyway, as you can see the sala is a bit of a distance from the small farm building where I installed  the circuit box, and I rather not have to run wires from there all the way to the Sala. So the guy who is helping my with the electric, said no problem . we can splice into the feed wires in the pole shown in the first picture, and run power from there.  The main Circuit breaker panel  in the farm building has RCB in it 

 it .

This is the box in the farm house. 

 

  So the question is would it be a good idea to splice into the feed wires, and install a small 2 breaker box in the sala, or would I be better of biting the bullet and bringing power from the farm house that already has a  the circuit breaker box with RCB?

I looked at two breaker boxes and all I could find on line was without RCB , (I am a bit apprehensive using a box without RCB).

  second question, would I need an additional ground wire for the sala if I added a small circuit breaker . or should I ground on the frame  (again apprehensive) of the metal sala? 

I appreciate any advice.

I would be quite happy branching off the incoming supply with a couple of "vampire" (insulation-piercing) splices, no need to strip the incoming cable!

 

Get one of these https://www.lazada.co.th/products/safe-t-cut-4-smart-life-f1-4-i2417866062-s8314215061.html? baby consumer units to go in your sala (the 32A one would be more than adequate). It will need a weatherproof box. I'm sure smaller ones with just the RCBO and one or two breakers are available.

 

You may be able to find an actual weatherproof unit with a bit of searching on Lazada.

 

Bang in a local ground rod, you could use the sala itself, but without actual earth testing kit I'd use a new rod. Bond your sala metalwork to the new rod.

 

EDIT Is the supply on the poles fed from the main building box or is it the incoming supply from the meter??

I did not see any. Lazada is very funny with their in english search function. I do a search on lazada and I get crappy results, then I do the same search on google, and a bunch of results come back from Lazada. I will take a ride to Do home or global house later and have a look. I was just researching the issue this morning and thought i would ask. 

Thank you I appreciate the help.

For the IPC chaps you will likely need a specialist electrical place, Lazada have many but all ship from overseas.

 

These are the cheapest I've found.

DoHome/HomePro/Global has the small consumer units starting around 800-1000 baht, many with 4 breakers.  I believe they also have DIY boxes without breakers, but cost of buying individual main and 2 breakers would be about the same as the complete set.

EDIT Is the supply on the poles fed from the main building box or is it the incoming supply from the meter??

So I found this one  on Lazada but it has two different options and I am not sure which one of the two to order

https://www.lazada.co.th/products/-i3077074926-s11299848218.html?

These are the two options

and 

image.png.cc21b0fbaf936fa45cdf7cfaede44b74.png

not sure what the above numbers mean . I assume they are for a range of sizes 

What I have existing are  two wires 50 aluminum and are for 30 amp service, The CB box is 63

The wires that I will be splicing are a bit smaller, from a 15 amp  service that I have leftover  , the Sala where I am bringing power to. will only have a light and outlet to plug a fan or something. so the thinner wires should be fine. 

If someone can help me pick the better option from th two. I would appreciate it.

This one can use wires from 6mm2 to 50mm2 on the main and 6mm2 to 35mm2 on the tap.

Ok one more question and I am done!!

for today:laugh:

Since I ordered the insulation-piercing thingamajig and would have to wait.

I thought I order the Circuit breaker box from lazada too.  

All I need is a two circuit breaker box. One would even work , but it seems a two is the smallest option, which is fine.

Anyway much to my surprise there were a whole bunch of them with many different choices, and acronyms. I think RCBO   is what I am looking for.

I chose this one, because it only had one choice, and I don't want to order the wrong thing.

What do you all think, is that a good choice for what I have in mind, or would another be a better choice. I am open to suggestions since I have little experience with this things here in Thailand.

  Back in the states I would know exactly what to get, and if I did not I could ask. Here I have to ask the wife to translate, and she does not have the lingo to translate , its a mess,

I got to go back to school and learn the language.

I went for a few months , then I decided to take a little brake. That was two years ago. :laugh: I tell you one thing Thai is a difficult language to learn.

Looks OK to me ^^^ :smile:

 

I've been here 19 years and my spoken Thai as at about 18-month old kid level. I understand a lot more than that but being somewhat deaf I don't really hear the tones and so I fail to be able to imitate them. Like Cantonese (another tonal language) getting the tones wrong is always rude!!

 

You want a hard language, try Tagalog. Even the Filipinos would rather use English!

Yea I am tone deaf also. I try to get the meaning dfom the context. I can speak a little but other than simple sentences, I find it difficult sometimes to separate the words,especialy from people like my sister in law who starts a new word before she finishes the first. :smile:

Anyway thank you for your help.
