Need help with typical relay circuit

Hi,

In answer to your questions:

- a switch

- a motor

- 220volts

- unknown

but all I really need is some examples of how to draw a relay switch.

Rob

More info is needed.

- What will be energizing the relay's coil? A switch, a contact, an electronic component (SCR, Transistor, etc..)

- What will be controlled by the relay? Motor, lights, etc..

- What is the Maximum Voltage and current of the device being switched?

- What is the importace of the circuit? Does it need redundancy? Fail Safe protection?

May I ask why you're doing a 'job' that you apparenly don't know anything about ?

Your answer is still very general. I suggest you seek the help of a licensed electrician. In the US one must adhere to the NEC codes as well as local codes. This is for very good reasons! You don't want a first timer wiring a pool filter, or a hot tub! There are code requirements that go beyond the basics of just turning the motor. Such systems have ground fault protection circuitry as well as specific ground schemes.

-You did not mention how big the motor is! Most likely you need a "motor Controller" which is a type of relay, but heavy duty.

-You did not mention the control voltage needed to switch on the motor!

Hard to guess what you mean by 'typical', and whether you mean *just* the relay or also the circuit that drives it. But here's one to get you started:

Replace the load with a more 'representative' motor symbol if you prefer.

Also known as a "Motor Contactor"

A schematic, or a wiring diagram? They're very different things, you know.
