I’m just getting round to wiring my bench and plan to put the machine and router on the same circuit complete with a E Stop/NVR switch so if needed I can stop the machine and spindle together,
The problem I have is knowing what size MCB I should use for the circuit, my options are 6, 10, 16 or 32 amp. I will also be putting the router through a fused on/off switch so I can isolate the router whilst changing tools or switch it on and off without reaching over the machine. see picture and not sure if I should change the 13amp fuse to a smaller one.
Thoughtfully designed and built - looks great as well. If ever you ever have need to remove the top, might I suggest you place a metal strip to protect the AC cables at the top right - just in case you or a future owner nails or drills through the top and into the live wires. it could be attached to the bottom of the top above where the cables run.
Hi TM, appreciate your comments, the top isn’t going to be fitted until I’ve finally located my machine and I must admit I did think about putting the 220v in conduit in the first place, so may have a rethink about that, better safe than sorry.
I think I may go with the 10amp mcb, I can always change it if it keeps tripping.
Hi Buddy - the controller requires about 5 amps and the router pulls about 6 on 120v. The vac usually pulls around 11amps. Derate all 80% and you should use >13amp breaker - probably 16 in your case. Same for vac alone. If it’s 220, then everything divided by 2 or so. YMMV.
For those of you who were kind enough to reply to my post before, here’s an update, nearly there, need to get a replacement z axis cable to repalce the pig’s tail, but where do I get one from?
