120Volt EH10 7-day 120Volt programmable timer Nema1 Programming steps and wiring appear on inside of timer door so they cannot be lost. 6 ON and 6 OFF programs per week. Terminals 3 and 4 are dry, and can be used for 24Vac transformer and 24V coil contactor: Connect power to terminals 1 and 2. Do not install jumper wire between terminals 2 and 3. Connect wire from transformer to terminal 3. See illustration of dry terminal wiring scroll down to ET1725 timer. AA battery located below timer buttons.

How to wire 3-phase outlets and surge protectionCooper brand outletsWire color codes at Wikipedia 3-phase wiring Line-to-line voltage = line to neutral x √3 3-phase has 2 varieties: 3-wire: three hot wires and no neutral, and 4-wire: three hot wires and a neutral |  Types of phase wiring |

Phase WYE 480 volts across line-to-line 277 volts line-to-neutral
| Voltages are higher or lower based on windings inside the transformer. Power is generated at plant by rotating 3 coils in a magnetic field => power is sent out on 3 lines => power travels over wires to local area => power lines are connected to transformer => power is changed into specific voltage depending on which transformer is installed, and how the transformer is wired. WYE or Delta configuration refers to how the 3-phase transformer coils are wired. Inside each transformer are two coils: Primary coil is connected to power generation side. Secondary coil is connected to service wires that feed the service panel and circuit breakers. If secondary coil is wound in WYE, then power to the service panel will always have a neutral, and two voltages. Read |
