If your motor is 4.5kW using your method you would do the following:

4.5kW in Watts = 4500W

4500W / 3 = 1500W (This is where you divide the power of the motor by 3 for the 3 phases)

1500W / 230V = 6.52A (This gives you the current per phase)

6.52A * 1.1 = 7.15A (This applies the 10% for max operating current to flow without overload)

No Problem, if you need help with anything else, just ask.

Good Luck Tomorrow!!!

Im pretty good with everything else, safe isolation and risk assesment im okay. Install okay as far as im concerned only the s plan heating I think will throw me off as i know I will over complicate it!! Testing im quietly confident and fault finding will be me hoping for 7 faults on the data.... lol!

Cheers though, ill let you know!

Surely it cant be as easy as taking a single cable from room stat terminal 2 to the main wiring centre terminal 5?

 

[Jamchiv01]

You would run 3 core + cpc from the roomstat back to the wiring center. Sleeving all cables appropriately. My drawing just shows how it needs to be connected.

Just remember the order it switches. programmer to thermostat, thermostat to valve, valve to boiler and pump.

Oh yes, my bad! But surely some will require just a single core no? The orange for instance?

 

[Jamchiv01]

No , The Valve comes with a 5 core cable pre-attached.

Grey = Perm Live
Blue = Neutral
Green / Yellow = Earth
Orange = Boiler call (SW)
White / Brown = Valve Call (Just noticed on my diagram I didn't label the brown from the valve as white as both colors can be used depending on the manufacturer)

I will update that now
