Hey I have a little project i want to do but due to the high current am sort of tempted to gather more info. I want to switch a washer machine off/on using a PIC. Ill give my reason at the end.
I went online and found a typical washer machine uses 500 Watts. Now to get the amp usage i did
500 watts / 120v = 4.16A so would be it safe to assume thats how i calculate the amount of amps it uses?
So to make a pic switch it i would need a relay that can handle 120v @ 4.5A minimum right?
To turn on the relay i would think it would be safe to use one of those infrared transistor things i forgot the name. Phototransistor i think?
I like this:
Multi-Channel Full-Pitch Phototransistor Optocoupler
Which can be bought for like $0.40 @
ACPL-827-000E|Multi-Channel Full-Pitch Phototransistor | Newark.com
and
This for a relay. Would be ok?

This is based on if my washer machine is using the typical. If not i will adjust parts. But would i go about this situation like this? Would this be how i calc and gather info for doing this project?
My Reason:
I have relatives that come over on daily bases and they are always using my machine and my soap and everything ... next thing you know i have to buy more. Im tired but dont want to be disrespectful to them so i want to make this switcher which i will had a remote to also. So i can turn it of wireless-ly and turn it on the same.
