T-101 timer controls 3-phase Use T101 120Volt timer to control 3 phase loads. Same wiring diagram as above can control 3-pole contactor. Neutrals connect to terminal A Hot from breaker connects to terminal 1 Hot to contactor connects to terminal 2 No fuse required on incoming line. Fused disconnect required on 3-phase line and timer in most commercial applications Resource: 3-pole contactors |

T-101 timer controls any voltage/ single-phase or 3-phase The 2 and 3-pole contactors with 120 volt coil can be used to switch any voltage and amperage load on-off. This gives switching control for 208-240-277-347-480 volt,50-60-90 amp 3 phase or single phase loads. Buy contactor with 120 volt coil, and match the amp rating of contactor with the amp rating of load.

 Override with switch Larger image |
Override
T100 series timer with 40 amp switch T100 series timers are rated 40 amp, 5 HP max Using a 40 amp motor control switch allows you to override any load that the timer successfully controls. Install switch inside any switch box. Watt or power consumption should appear on rating plate for each Load (motor, fan, lights, appliance etc) Divide watts by the voltage ... in this case, the voltage for T101 is 120 ... so if load consumes 3500 watts divided by 120 volt = 29 amps. This is within the 32 watt safe maximum of any 40 watt switch (safe maximum = 40 amps x 80% = 32 amps) Buy: 40 amp switch with 32 amp safe max Motor switch MS302 30 amp 2-pole switch Buy 30 amp switch with 24 amp safe max: 30 amp motor switch 30 amp 2-pole switch 30 amp industrial grade Leviton 3033 switch 30 amp 3-way switch |

 Larger imageOverride T101 using 40 amp contactor and freeze thermostat --A freeze thermostat or freeze switch will turn Load ON when temperature drops below 40°F, and then turn off when temperature rises again. -Low cost way to turn on pool or irrrigation pump or heater etc when freezing temperatures are expected. Note the contactor coil should be 120 volt, or same voltage as timer. -When temperatur drops, then the freeze thermostat completes circuit to the contactor coil. Contactor coil pulls the switching terminals together, and overrides the timer, turning on the Load. -Contactor is approx 2" wide, 2.3" long, and 2.6" tall. -There is generally NOT enough space in the wiring compartment of T101 to add a contactor. The contactor must be installed inside an electrically rated enclosure. Buy:  Freeze

| Wiring Tips | |
 |
Keep wires straight Use solid copper wire If wiring terminal or end of wire are covered with green, use emery board to clean terminal and sandpaper to clean wire. |
  Larger image |
Both wires MUST be same gauge Straighten each wire If wire is corroded or overheated, clean the end with sandpaper and wipe with cloth. If wire has been melted, cut back and reattach, or replace wire. Tighten screw very tight against copper wire |
|
 Use wire connector  Use push-on wire connectors |
3 wires/
or different gauge wires Join wires with wire connector or push-on connector Run jumper to screw terminal. Buy: Red 3P connector (shown) for 10-14 gauge wire Lever connectors for stranded wire |
|
 |
Fire safety/ Do not put stranded
wire under screw plate Do not install stranded wire under screw. Problem1: picture shows 2 different gauge wires under screw plate Problem2: Stranded wire will expand and contract and come loose under screw plate, even if it is the only wire under the screw plate Attach stranded wire and solid wire with wire connector, and run solid copper jumper wire to screw terminal Take photo of wires before starting.

 | Installation tips -Secure wire or conduit to enclosure. All wires, enclosures and conduit must be secured to structure. -Always use solid copper wire under timer screw terminals ... stranded wire can come loose and cause fires. -Keep enclosure door closed to prevent possible fire hazard from spreading. -Keep insulator over screw terminals to prevent accidental electrocution hazard. -Install enclosures away from hazards such as lawn mower or machinery. -Install outdoor boxes in sheltered area if possible and 12" above anticipated snowfall. -For safety, make sure Load is grounded correctly. People often forget to securely join the ground wires inside timer because wire sometimes gets a bit short. Buy extra length of wire from box store. Load must be grounded. Why you need ground wire | |
  12 Ga |
10 gauge or 12 gauge? Compare your wire with short pieces of 10 and 12 gauge wire from local box store 10 gauge for 30 amp breaker. 10 gauge wire can have black-white and sometimes black-red 12 gauge for 20 amp breaker 12 gauge will have black and white wires Buy: Southwire romex cable Resources: Match color code and amp rating for wire Basic house wiring |
 |
Add black tape when White wire
carries voltage (applies to 208 and 240V circuits) With 120 and 277 Volt circuits, White wire is Neutral, and Black is Hot With 208 and 240 circuits, both wires are Hot, and both wires carry voltage Black tape on White wire identifies wire is Hot and not Neutral |
 |
Use correct wire and breaker Oversized is OK, undersized is hazard Look at label on load to determind correct size wire and breaker Watts divided by volts = amps If Load is 120 volt, and watts is 1500 = 12.5 amps. Next calculate 80% safe maximum. 20 amp breaker x .80 = 16 amps safe maximum 15 amp breaker x .80 = 12 amps safe maximum The calculation shows that 4500 watt load requires 20 amp breaker and 12 gauge wire up to 150 feet. Longer distance, use larger wire and breaker. Buy from my affiliate links: Southwire cable and tools Resource: Figure volts amps watts |
