Where units of horsepower are used for marketing consumer products, often
measurement methods are designed by advertisers to maximize the size of the
number produced for any product, even if this may not reflect realistic

Thanks for the information. I never did, and probably never will,

One Horsepower is generally considered to require about 750 watts.
so 2.25 HP will need a solid 1700 watts. This is probably a peak rating,
but none th less it must be on a 20 amp circuit that isn't used much.
If you have a coule 200 watt outside lights on at the same time, it will

Edward,
3.5 HP times 746 watts per HP over 120 volts is over 21 amps.
so they're probably lying about the hp, but you could sure pop a breaker

1 horsepower equils 746 watts so a 2.25 horse motor equils 1678.5 watts.
Dividing 1678.5 watts by 120 volts and you get 13.9875 amps.

David,
seven hundred fifty watts per horsepower,
thus the typical fifteen amp circuit might just make two horses,
theoretically but with start up surge currents probably not.

motor operating off a standard electrical outlet. I know it isn't much,

If you have a standard 15 amp circuit at 120 Volts, that is 1800 Watts.
There are 746 Watts per Horsey. So about 2.4 HP from a 15 Amp circuit.
Bump that up to a 20 Amp circuit, 2400 Watts and you get up to almost 3.5
HP.

Bob,
Just pointing out the wide variation between what theory says is possible,

means that it would draw 20.2 Amps at 120 Volts if the motor was perfect.
So, no I don't really believe that your router can continuously
So, not surprisingly, theory and reality are at odds. The 20 amp times
120 volt divided by 746 watts per HP, gives the theoretical value.
Luckily, we have folks on the list who know a lot more practical knowledge
than someone like me with a bunch of theory.
Reality appears to be that you are
