Thread: Electrical wiring, the proper way.

^

Lack of a proper Earth no doubt and a dodgy install.

There was a tourist killed in Pattaya a few years back whilst walking through a puddle in the road. https://teakdoor.com/thailand-and-asi...trocution.html

There are some qualified Electricians on this forum, I'd love to hear their take on the 10MM cabling to the friggin kitchen oven.

This is the correct size for the load and run distance.

The only problem with large conductors like that is that they are difficult to pull through conduit.

Mate, seriously,

If you are a qualified Electrician and you are telling me that using 10 mm twin and earth cable to wire a standard house is a good idea I suggest you go back to Electrical school.

If volt drop is the problem the correct way to do it would be to use the 10 mm as the run in from the power source to the house and then wire the house with the correct size cabling, that being 2.5mm twin and earth for the power and 1.5 mm for the lighting circuit.

Jesus, where is Baldrick ?

He is the electrical expert on this forum and will put this stuff to bed in 2 seconds.

10 MM wire for a standard house install.
bolliks.

Using 2.5 mm power cable is sufficient enough to run every house hold appliance 24/7 without any problem what so ever as long as the house and appliances are wired correctly and the correct voltage is being delivered to the house.

If the correct voltage is not being delivered to the house it would not matter if one used 50mm within the house, the system will not operate correctly.

2,5 is too small for showers ovens etc etc, what mud hut do you live in?

Heh...Here we go...

Forget to allow for trolls. Oh well play on.

^Where's Baldrick?...

Unfortunately any thread where I am Baldick steers well clear off.

Baldick don't like me very much, Actually I feel it goes much deeper.

Oh well, such is forum life Heh.

Bit of a bummer in this situation, one can never question his Electrical knowledge.

Foker gets paid squillions for his knowledge.

No shit...Well, maybe he'll make his way over and add his two bits...

Subtle, but effective.....

Urm,

Thanks for that but I cannot remember the figures to enter in.


I'll just rely on what the Tradesman taught me when I wired up the hundreds of houses I have done.

Never used 10MM in any of them.

Of course not as its fookin not done on residential domestic installs.

Good troll though.

Amid the quietened halls of the forum an audience gathered, awaiting with bated breath for the 'Seer of Circuitry', the 'Wizard of Wiring', the 'Sage of Surge' to appear offering divine assistance.

The 'Warlock of Wattage' finally emerges in all his splendour, scratching his nether regions and shatters the silence created by his neophytes with.......

And thus spake 'baldrick'.

And thus spake 'baldrick'....


only to be greeted by Terry57 with ..

Is Terry57 questioning Baldrick's electrical knowledge, his expertise, or just the link he provided? Who's the troll Terry?

Best option - just ignore Terry in all ways. Problem solved. Then there is no problem.

Terry is obviously not wired up right.

^Thanks for your valuable input AnalAndy...Now charge up your buttplug with 10mm wiring and fck off...

Cablesizer | Cable Sizing Calculations to IEC and NEC Standards

240V, single phase, copper conductors, 6kw load
"The minimum Single Core cable size is: 10.0 mm2"
"The minimum Multi Core cable size is: 10.0 mm2"
*Same for 20C ambient temperature, same for 220V, same for single core cables, same for multi-core cables.

240V, single phase, copper conductors, 5kw load
"The minimum Multi Core cable size is: 6.0 mm2"

240V, single phase, copper conductors, 4kw load
"The minimum Multi Core cable size is: 4.0 mm2"

240V, single phase, copper conductors, 3kw load
"The minimum Multi Core cable size is: 2.5 mm2"


So, we can gather from this thread that Australians in Perth only use 3kw shower units - or Perth sparkies don't shower at all.

You are welcome, Terry.

That is excellent observation & thorough logic, Sherlock.

^Nice new av there, cnx...People look at you in a new light, now...

Well done...

I know the answer to that 100% for sure. In Thailand the neutral carries a voltage of 2-3 volts. Connecting it to your earth will give you a mild shock if your shower is earthed and you touch any of the metal parts of the shower. You DO NOT connect your neutral to earth in Thailand.

Our phase went off recently (transformer blew up !). The fans just ran a bit slower,the tv still worked ok. Confused me until I found there was 75 volts on the neutral to earth. Go figure.
(If the UK wiring regs are so brilliant,why are we now on issue 16,or is it 17 now????

It was because of 'back feed' on a three phase line. One phase goes out but the remaining two phases 'back feed' through another three phase transformer bank, albeit at a lower voltage.

It was spot on, Exactly how things would be done in the real world.

Power points, water heater and Air Con all wired in the correct sized cable, that being 2.5 ML twin and Earth.

Lights wired in 1.5 Ml and the main Earth wired to the Earth Spike.

I could not establish if the 1.5 Ml light cable had an earth.

In the real world this is a must.

Anyway, if one wants Electrical work done properly go to the Government approved office and not Somchai the Back yarder.

Thailand does has correct standards if the proper people are sourced.

Up to You.

Somewhat ironic that the new install inspection team of two from PEA...walked in our house looked at the service box without opening it,asked if we had a ground and a GFI, nodded and left.
Still don't understand why so many appliances come with Schuko plugs....defeats the object of grounding..never seen any outlets available?

On the ongoing debatable subject of grounding and or ground to neutral bonding:
While a grounded appliance offers protection against fire, it is not a guaranteed protection against electrical shock. In the event of an insulation breakdown or similar fault, unless sufficient current is leaking to fire a 15 amp or perhaps more breaker the appliance will still be live.
Only sure protection is a leakage protection breaker (Safety Cut or). Whole house plus individual separate units for pumps and shower heaters.
I wired our house and bonded ground to neutral..Good idea?..Not sure since, as one poster pointed out, your house could become the defacto return for your neighborhood in the event the ground/neutral in the network fails.
