ALWAYS SHUT OFF POWER BEFORE STARTING A PROJECT SUCH AS This. if YOU ARE
UNSURE "CALL A ELECTRICIAN"
For this project you will need the following electrical components:
110v-120v single pole-single throw time clock.
Minimum 30 amp continuous load contactor with a 120v coil.
A control box to house the contactor and or both the contactor and time clock.
Of course you'll need wire, mounting screws, terminal adaptors, wire nuts and a power supply
The above may not be a complete list of electrical components and electrical supplies depending
on your application.
Time clocks are marked for line and load. A contactor will have two connsctions with either
screws or terminals for spade adaptors and are most always marked "coil".This will be where you install the
control wiring from the time clock.Install the load
wire from the time clock to one side of the coil and the neutral wire to the other side of the
coil. Verify that is the correct voltage to your application.
On the contactor the most commonly recognized way of installing your lines and loads is LINE on
TOP and LOAD on Bottom.
The dotted lines refer to your neutral, the solid black and red lines refer to your power
source (line) and your (load) to the lights or device.
Follow the electrical wiring diagram I have shown one step at a time and it should be a simple
Print out this page and have it with you while installing and wiring this project.
After your sure that your supply source is shut off take the following steps:
Install control box if used.
Install Time Clock
Install wires as shown.
Be sure that you use the correct size wire for the circuit you are controlling. IE: 14 gauge
for a 15 amp circuit 12 gauge for 20 amp circuit.
You should have an above average mechanical ability to perform this type of work.
