AMP ratings for common appliances?

I know somewhere I've seen a list of common appliances and their ampere draw, but I can't find it. I'm trying to determine how much of an inverter I'm going to need.

Appreciate any help.
Thanks

scattershot,
Recently I have been reading as much as I can find about inverters and solar and ran across this site which is very helpful:

Two other sites help if you are interested in wiring an inverter into your system:

While most appliances are rated in amps, some are rated in watts. To convert watts to amps, divide the watts by the voltage. For example, 480 watts divided by 120 volts would be 4 amps. Your appliances should have tags on them listing either the amps or watts, but it may be hard to find them as manufactures seem to assume we don't care about that stuff and put the tags in god awful places.

Thanks, guys, good info. Jolu, that is a great site. Thanks. I'll bookmark it so I'll have it handy.

This stuff is confusing, isn't it?

Tom, that is also good info. For example, if you have a 1500 watt hair dryer (industry standard), and you are plugged into 30 amp, that will draw 1500/120 =12.5 amps. This is about HALF of your total 30 amp capacity (if you are fortunate enough to have very good CG wiring).

I know I am not the only one to have the pedestal breaker trip while the wife is doing her hair...
