The one in the link will be fine.

Don't worry, the capacitor from RS is rated for 440 volts working AC which is what you need. I think the one ndiy was referring to is 40 uF which is 10 times too big anyway.

Hi All

Replaced on/off switch as wasn't switching neutral. Seems to be working OK and cutting fine with the capacitor I have shown in my previous post. Hopefully this will be everything.

Anymore advice welcomed and thanks for all your input.

Best get the correct value capacitor in stock so you don't have a lot of down time if the one you have fitted fails.

Hi,Why do people post information that only confuses the original poster and also in some cases is wrong ?

Read my posts. I did not refer to any particular capacitor. That RS capacitor, if it will withstand 440V A/C Will certainly withstand 254V AC.

254V requires a capacitor that will work safely at 360V DC - but it must be a non-polarity conscious type.

That 440V AC one should withstand over 620V either side of zero volts. So plenty of safety margin.
