Jazz,
Sorry just checking. I thought maybe I had upset you and not realised it. Thanks for clearing it up.
Birchy I would seperate the supplies for the cooling fans and fit a seperate fuse or mcb for them. The amount of times I have seen fans sieze up and take out control circuits isnt real. What rating is MCB1 going to be? Just wondering about the descrimination between it and the fuse for the WM16, a fault here might bypass the fuse and take out the mcb.
