Underground cable to new house (HDPE+NYY)

Recommended Posts

Guys,

 

I was reading this topic and specifically this post

 

There it says. (Translation from the Thai Text)

 

Quote

Remark - Copper cable must put in PVC pipe using separate cables underground use NYY only.

 

Would this mean for our 15/45 Meter which we are going to connect to the house using NYY, that I would have to run 2xHDPE from the Meter to the House or is one enough?

 

Thx in advance

Just one.  If you have not yet contacted your PEA, be sure to do so for the point at which you intend to go underground.  Most PEA do not allow under roads, easements, and the like.  Once on your land, up to you.

Thx Perfect.

 

Will contact them before we lay the HDPE.

 

Thx again, really appreciated.

Yeah ^^^. My understanding is one pipe but separate single-core NYY for each phase and neutral.

 

Bus as above, talk to your local PEA before you do anything.

It would be a 2x16 NYY to connect the house to the Meter, that is the recommendation of the Sparky.

How far is it from meter to house?

 

A 2x16 does NOT meet the requirement of separate cables, do verify that your local PEA will accept.

@Crossy what do you think the logic is for needing separate cables?  (vs. 2x)  Esp. in NYY.

Approx 60-70 Meters from the meter to the house.

 

Will do, will verify about the 2x16 and the HDPE location

 

Thx

Purely on a volt-drop front I would be tempted to go to 25mm2 if budget allows.

Oke and then in a 40 HDPE? I was thinking about the 32 HDPE for the 16.

 

Correct?

Single NYY in 25mm2 is 14.5mm in diameter overall and you need to get two down the tube.

 

If reasonably straight 40mm ID tube should be OK, go bigger rather than smaller 🙂

Yeah you are right, in the other thread it already said it was difficult to pull NYY through the tube, and with 25mm2 it would way harder and also I will (I think) need (1 or 2) 90 degree bends, which will make it even harder 🤐

 

Thx guys, really helpful, really appreciated

 

Will update when I have news from our local PEA.

A 25mm2 x 2 NYY is the best part of an INCH in diameter, that's going to be a wrestle to get into your tube.

 

The 2 x single core version would be more manageable.

 

Either way your man will need specialist pulling kit.

When digging in my yard, trying to find where a drain pipe was blocked, I found that it was buried about a meter down and simply stubbed off. They never got around to hooking it up to the rest of the drainage system

However, about 30 centimeters down we came across the main electric feed. Glad I wasn't using a pickaxe !!

Is there a Thai word for "code"? If so, how much does it cost to get a pass?
