Hi
Need some advice. I need to upgrade my two showers from 4500wt
To 6000 wt units.
I was going to upgrade the wiring to 4mm square. 3 singles in yellow pipe.
From the old 2.5. square in yellow pipe.
Plus a new RCBO breaker 32 amp Schneider type.
Now the new shower unit is going to be a sharp SHARP WH-X HOT6
( not bought yet)
But looking at the installation manual. It states use 6mm square wire double insulated.
My run max length will be 10meters max, do I really need 6mm square double insulated wire.?
I’m not an electrician so unsure.
Don’t want to try and get 6mm wire down a tube in a wall if I can help it.
Any help would be great.
Thanks.
