Hi all,

This group often sees questions about ratings (can my 2 hp electric
motor develop 3 hp? can I draw 150 A from my 100 A supply? etc.) so I'd
like to ask a rating question. I think this one might spark some debate.
If you buy a good electric motor, the power rating is a continuous one
(or it says otherwise). Same with most pieces of industrial equipment.
But what about a car? Is the 130 hp or whatever maximum engine power the
manufacturer quotes a continuous or an intermittent rating? I was always
under the impression that it was an intermittent rating, though quite
where I got that idea I can't remember. I'm not asking if the engine
will wear out quickly developing its maximum power rating continuously -
I'm sure it will - I'm just wondering if it will overheat?

Any thoughts? Just a matter of curiousity...

Best wishes,

Chris
