Can you replace wall light switch with a PIR switch if Wall switch has usual live neutral and earth but PIR has live in live out and neutral.?
An ordinary light switch does NOT have any neutral -- it only switches the live wire. Some installers use the white wire as a "switched" wire to the light fixture, where the power cable went to the light and a separate cable went to the switch. Technically, the white wire should have been marked with red or black tape at each end, to signify it is not neutral - it is either live or off. In that case, you would not be able to use a PIR switch because there is no neutral, which is necessary to provide power to the electronic circuit in the PIR. You would need to rewire the switch with a new power cable from the branch circuit. The you have the live and neutral wires in the outlet box, connect them to the PIR, and run the pigtailed neutral and the switched live (and pigtailed ground) to the light fixture (where you would disconnect the other power cable completely and cap the ends separately).
How do you wire a series of recessed lights to a single switch when the power goes to the lights first?
If you already know how to put one fixture on a 3-way, just connect white-to-white and black-to-black from one light to the next. If you're changing from a single switch to the 3-way, the exact wiring will depend on whether the power comes from the breaker box to the switch or the existing fixture. I'll assume you're starting from scratch or have the power going to the fixture. You need #15 two-wire with ground and #15 three-wire with ground romex. Run two-wire from the breaker box to the first light fixture. Pull a another two-wire from this box to switch A and a three-wire between the switches. String two-wire from the first light to the second, second to third, etc. In the first box, connect white from source to the white fixture wire and the white going to the second box; black from source to the black to switch A; and the black fixture wire to both the white to switch A and the black to the next fixture. At each of the other 5 fixtures, connect all white to white and black to black (three pair in each box except the last one). At switch A, connect the white from the fixture to the common (center) connector and the black directly to the black going to switch B. The red and white wires going to switch B are connected to the two outside connectors of switch A. At switch B, the black goes to the common connector and the red and white to the outside connectors. At each box, connect all the bare wires (second ground) to each other and to the fixture or box. Now turn the power back on. If all the connectors are tight, power should follow the black wires from source past the fixture and switch A to switch B. From there it will go through one or the other of the travellers and, if switch A is in the same position as B, up the white switch leg to the fixtures, turn on all the lights and go back to ground.
When wiring a wall switch which color wire goes on the common terminal screws?
A typical switch doesn't have a Common screw in the strictest sense, it just has two screws which are each side of the switch. You probably have a a 3-way switch. If you are hooking up a 3-way switch as a normal switch, then connect the Black (Hot) wire to the common and the load to the side of the switch that makes UP the on direction and DOWN is off and doesn't get connected. You can determine for sure if you have a 3-way switch because the word ON and OFF don't appear on the toggle.

Why would a light switch have two black wires for power and two whites caped off?
Black represents Hot and White common. For the light to operate it needs a white and black wires. The switch box has two cables with a white and black wire plus a ground. One wire is from the supply and the other to the light. Connecting the whites just provides common directly to the light. The blacks go into and out of switch because it is the hot side that is being switched.
Is a black awning cooler in the summertime than a white awning?
No, a black awning would actually absorb more of the light spectrum thus being hotter. A white awning would reflect more of the spectrum making it cooler. However the heat of the black awning would heat the air closest to it making it rise. The rising hot air would suck cooler air towards the awning creating a draft or air current which could make the air under the awning seem cooler. This same effect was noted in an article on burquas where the black burqa actually cooed the wearer.

The Rear defroster switch on your 1995 Ford Escort does not stayed engaged after pushing the button but will work if you hold it is there a relay for this function or do you just replace the switch?
replace the switch... there is a spring steel L shaped clip that goes around a V shaped slide and that plastic slide breaks on them... i have the same problem and looking for a used switch cause the ford dealers want $112.00(can) for a new one. I suggest buying any toggle/push-button switch and rewire it (as the ford switch will break again). A new switch from Radio Shack (or equivalent) is easy to install and will only cost you just $5. Here's the wiring info for your convenience: (The stock Ford switch is a 5 terminal switch) Red & black stripe - Hot for illuminating LED Black - Ground for illuminating LED Red - goes to dimming rheostat Black & White stripe - Hot "for" Rear Defroster Black & Blue stripe - Wire "to" Rear Defroster
