Hello all
Wonder if anyone can shed any light on this situation.
The problem is i have a Charnwood planer thicknesser the book say's it's: Motor ( induction) 3000w (4hp) 240v & requires a 16amp electric supply.
This machine is in my attached garage that has it's own hager consumer unit, The CU is fed from the house CU on a normal 40a mcb (about 10m) via a 10mm 2c+e. There is no other load from this garage CU, Just the commando socket at the moment..
The problem is.. Charnwood's website states a 16a connection is needed but the manual says 20a..
So.... The commando socket about 3m from garage CU is fed with a 4mm radial cable.
I tried the machine on a 16a rcbo type B , not a chance and tripping every time i start the planer, fine i guess...
Then tried a 20a rcbo Type B and it trips half the time on startup.
Now just tried it on a 32a rcbo type B and it didn't trip once...
Thing is this machine should really run on a 20a rcbo without tripping, not even as if it's cold at the moment.
Any ideas on this, could a 20a rcbo type C solve this?
Thanks
