The LINE wire is the power supply or hot wire coming in. It should have continuous voltage (be careful).

The LOAD wire goes to the device to be controlled.

How to change clock on intermatic t101p

Step 1:

Turn power off to time clock

Step 2:

Remove the wires, but mark them/label them from where they came from! Should be 4 of them. 2 on the posts marked Line and 2 on the posts marked Load.
Line wires are coming from your power source and will usually have the small white wires with them to provide power to its internal clock motor.
Load wires will go to the motor.

Step 3:

Near the top on the left side you will see a clip style holder. That holds/locks the clock into place. Push up on that clip and with a free hand grab the clock mechanism and pull. The clock should come down and out as you pull.
Take new mechanism and find its resting hook at bottom and just reverse the step above. It should slide into place & lock under that clip. You will hear a click/snap.

Step 4:

Replace the wires that you marked: the 2 Line wires and the 2 Load wires. Check the schematic and ensure that the positions are the same as old or not.
Some older clocks had this schematic: Line - Load, Line - LoadSome newer clocks had it this way: Line - Line, Load - Load

Step 5:

Tighten the screw nice & tight and ensure that you have line wires on the line post and the Load wires on the Load post.
You should be golden.

Thermostat Line Voltage How to Install or Replace

You either have a new line voltage thermostat or have to replace your old line voltage thermostat. In either case the process is much the same.


  1. Make sure that all power is turned off at the breaker panel. Most heaters that use a line voltage thermostat usually use 240v current so the breaker will either be a double pole breaker or you will need to turn off two single pole breakers to kill all of the power.
  2. Check to see which wires are hooked to the breakers. In most cases it will be the red and black wires, but I have seen many times that the white and black wires were used. Often there is no red available when the white is used.
  3. Take out the two screws that hold the thermostat to the junction box. When you get the thermostat out make a note of which wires go to the heater (load) and which wires are coming from the breakers. (line)
  4. If you have a single pole thermostat installed one of the sets of wires may be wired straight through the box or have the line and load wires connected directly in the box. With a double pole t-stat you will have both sets of wires running through the t-stat.
  5. Remove the old thermostat and wire the new t-stat in the circuit with the load wires hooked to the load or heater and the line wires hooked to the wires coming from the breaker. Make sure to get a very good tight connection as resistance loads will heat up quickly if good contact is not made. This poor connection can and will start fires.
  6. Turn the power on and check the heater for heat output.
  7. Turn the power back off and carefully screw the thermostat to the junction box securely. Then you can reapply the power to the circuit.

Now you are up and running with a new line voltage thermostat installed.

I have a 15 amp break that tripps due to over load in the amount of outlets being used, can I replace the breaker with a larger amp breaker to solve the problem

You will solve the problem of the breaker tripping but you'll create a fire hazard as the wiring may overheat because of what you are drawing through the line. If you need a higher amp circuit breaker for the load you are creating on the line, you need to make sure the wiring can also handle the extra load. You'd be way better off by spreading the load over several different circuits or installing another line to reduce the load on the line that's tripping the breaker.

2 black wires thermostat, which is load wire?

I'm not familiar with the model number but if you are installing a standard line voltage thermostat it doesn't matter which of the black wires goes to the load.

Clock does not turn on

make sure the small white wires coming from the clock itself are installed on the "line" side of the terminals, those power the clock. If not, the switch will power the pump but the clock will not run.

For an 3 Tn unit- single phase- 220 V a.c and gfor

There should be a full load amps or rated load amps on each of these units on the rating or nameplate. The ampacity or fuse size and wire size, which I think that's what you are wanting to know . The fuse size would be full or rated load amps times 125% and the wire size depending on the length of the run, 50 feet or less, (15 amps 14 gauge wire), (20 amps 12 gauge), (30 amps 10 gauge), and (40 amps 8 gauge).

I'm trying to install an Intermatic T104R3 for my pool. What is the difference between line and load? Do you have a picture of how the wires should be connected?

'Line' means 'power in' and 'load' means 'output' to the device you want to control. Hook you power in 'HOT' wire to line and your 'load is the wires going out to the motor or lights or what ever. Follow the diagram on the door.
