Is this really 230V?

[Richard]

On a big site today and we got asked to have a look at wiring a Readymix tower (cement silo).

We don't do alot with motors so please excuse me.

The plug on it was a BLUE 4 pin 32A type. Obviously no instructions.

I would have thought 4 pins = 400V wired in Delta? and earth (from my college days)

So why would it have a Blue cover? or is it likley to be the case that someone has replaced the cover with the wrong colour?

Please see attached a photo of the Data plate

Thanks

i think it's a dual-voltage wired in 230v delta probably

if i'm not confused again

The colour of the plug tells you it is 240v,yellow is 110v blue 240v red 415v,
so yes dual voltage wired on 240v.

Readymix tower gave the game away.
The site will be under M&Q regs. 3ph 230V is a common thing to find.
Just watch out on lighting circuits if they are on the 230V 3ph system, 2 pole fusing and switching is needed.
