Electric Motor Problem

[Andy Wade]

IMO it's almost certainly polypropylene (MKP), not polyester (MKT). Pretty-well all AC-rated caps for motor start/run and power-factor correction are polypropylene these days.

And how do you work that out, oh wise one?

Or coffee filters.

Stuartsblog submitted this idea :

I c14uF and rated 400v AC for temperature band A, with a tolerance of + or

- 5%. 13uF or 15uF would be fine.

[The Natural Philosopher]

No need for 500VAC. Its 500VDC to cope with 415V peak to peak voltage of a 230v AC RMS supply.

Actually its more like 275V AC..

[The Natural Philosopher]

NO. 400V DC is the rating, or around 250V AC. Most motot start caps are quoted as AC rated..

Is this in the same sense as "night soil" as a euphemism?
