If you're resident, nothing will happen.

If you're commersial, you get penalty.

Cause I’m running mining rig at 1 room.

I’m willing to pay for TNB but I not willing to trigger them (especially local council / any thieves)

My total rig at that room would be around 60A now.

Just use all the 3P to balance it.

As long as in resident unit, you're fine. They will just send a letter to tell you, you 're wasting the energy.

So can I do like this

Red = 5 power points (around 8kw / 32amp)
Yellow = 5 power points (around 8kw / 32amp)
Blue = 5 points (around 8kw / 32amp)

But all those I mentioned in a SINGLE room.

Make it more balance.

Yes you can.

Just make sure that you have zero chance that the phases touch or make contact with each other.

No problem.

It is not like how many power point. It is more how you balance the load.

For example, if you wired up 3 aircon in 1P (red), that is not balance load.

If you wired each aircon on each 1P, that is balance load.

So if you put 5 power points on each phase, But you plug in your mining rig on the yellow, no use right ?

Hi Sir,
Hope you can help me on this matter.
From the tnb meter (outside) to switchboard (inside), the underground armor cable should be one piece right?
cause i found out the contractor using 2 or 3 cables connect together. If you need to see photo, I can pm you.
is this the standard practice?

If 3 cable mean 3phase ?

You can always ask him why 3 cable. Don't think he will cheat you with 1 cable if running on 3phase.

I think he means 3phase4wire armored cable that's been joined.

To answer it's usually because the contractor has separate lengths of similarly sized wires thus joining two (or more) would save the spare lengths.

However since the owner is paying then insists that a new installation must not have joined cables since the cable conductor wire strands not properly connected and the joint if burried underground risks of water seepage.

So being the boss just reject that work and get a properly measured cabled installed.

Oh, Now understand.

That is dangerous and should reject the work.

Such a short distance for home lay and join few point? That contractor should have measured the distance before buy the cable length.

That cable is 16mm carrying high amp percable. Joining such cable require proper join and proper insulated which is not easy.
