you're referring (I think) the change to a type C fuse?? Now I'm not good with electrics so someone competent feel free to chime in and correct any terminology errors I'm about to make but its important to discuss the principle here because otherwise you may be sending the thing back for completely the wrong reason and any other manufacturers machine you replace it with will experience the same problem. I'm guessing you don't want that??
So Mr gardener above is a typical case. His breaker was the wrong rating ie a normal household one (type B???). When you start up a tonking great bit of cast iron like the block of a planar/thicknesser or the cast iron bandwheels of a bandsaw, depending on the motor size, they draw a lot of current to overcome the inertia of the components....that's what trips a regular household breaker. For workshop use, you'll be wanting the type C??? breaker which is more forgiving of startup load. It's not so much on a "hair trigger" and will allow a high startup without tripping. Incidentally, once the thing is running the power requirements are much less as momentum is involved so the fuse popping ceases to be an issue...its just on startup.
That's a typical and very common case for many and we've seen it reported here numerous times.
My case was slightly different and I'll probably even cock-up the explanation as I'm such a dunderhead with electrics but here goes to try and convey the principle. My consumer unit had 2 banks of fuses, some were not governed by an RCD and some were. When we plugged the lathe into a plug socket that was governed by the RCD it tripped every time but using the non RCD sockets it ran fine. They both had the regular household type B??? fuses mounted so it clearly wasn't that. What Bob did to fix it was open up the consumer unit and move the appropriate fuses (that led to the sockets in my garage) so they weren't controlled by the RCD. They now work fine. Don't even try and explain why that worked because you'll start using terms like "earth leakage" and I'll lose the will to live!
Anyway, its really worth making sure your sparky isn't talking out of an orifice in his body, not normally associated with verbal communication BEFORE you send anything heavy anywhere!!
