Replacing motor capacitor.

[TomT]

I ordered a replacement 100uFcapacitor for a 2.2kw single phase Brook motor. It was much larger than the original and marked 100uF 415V. Will it still work or should I get a smaller one?

Your new one has a higher voltage rating than the old one so it is "better".
Swap them over. It should be fine.

And if you are wondering how to hold it in place, as I did with the same problem some years ago, use cable ties as the original straps/clips will not fit.
