This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.
The line side is where the source of the voltage is connected. The load side is where the device being switched is attached. In the case of a light switch the line side would connect to the house power and the load side would be the bulb. The switch is usually inserted in the line carrying the load (or black wires). As it it common to use 12-2 wiring to run from the device being switched to a switch on the wall, the return wire can be colored white. A electrician places an identification on the wire to signal that it is a "hot wire" even though it is white. Typically the electrician will wrap the white wire with black tape for about 1 inch to indicate this. A white wire is normally considered to be neutral if it is not identified as a "hot or load wire".
Connect the black wire to the incoming hot wire and the red wire to the out going load.
because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times
House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.
The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.

The Load wire is always hot (black or red wire) and the Line wire is the one that returns to your fusebox (usually white). Answer above is absolutely wrong written by someone who does not know electricity and will get you electrocuted. The white wire is your neutral wire. The black or red coming from the electrical panel is the line wire. the black or red wire going to the next outlet or light fixture is your load wire. in some cases a white wire will be a line or load and should be indicated with black tape on it denoting it is not a neutral. quick recap is Line = power in, load = power out.

In household wiring it is the "hot" wire that carries current to the load.
Connect the black wire to the incoming hot wire and the red wire to the out going load.

A 12 gauge wire can support a load of approximately 2200 watts.
Black wire to gold screw, white wire to silver screw, ground to green screw. If you are using a GFIC outlet then the hot wires coming in hook to the Line side of the GFIC receptacle and the wires going out to other receptacles hook to the load side.
Load (or hot wire, usually black or red), Neutral, (white), and ground,(green) wire.
Remove the light sensor and place a switch between the red and black wires. The black wire is one leg of the "hot" pair and the load is connected to the red wire. This will now switch the black hot through the red wire that goes to the load.
