What type of relay works best here?
Look at: http://goo.gl/lkfoi which is rated 1 HP at 120VAC. Typical 10A rated relays are probably not OK for the startup surge on the motor.
Hi guys im interested in doing a small scale version of this.
What I plan on is having 1 Ds18b20 set up to trigger a relay at a set temp limit. ...Could anyone give me some pointers or point me in the right direction?
Big electric motors typically use something called a 'contactor' rather than a relay. They seem to be fundamentally the same thing (solenoid operated switch) but are presumably optimised for switching high current inductive loads.....
