how many times do you walk into your laundry room and you can't turn your lights on because your hands are full of clothes this happens to me all the time and with stinky clothes I might add so today that's why I'm installing an occupancy switch this is the maestro by Lutron it's also known as a motion sensor switch so if you want to be able to turn the lights on automatically this is what you need let's get started it goes without saying but I'm gonna say it anyway you need to turn the electricity off to the switch that you're working on do that at the circuit breaker okay before you do anything else safety first after turning off the circuit breaker remove this faceplate what you can do now is test this switch for electricity unscrew the mounting screws that hold it to the electrical box okay hold on to the tabs okay pull it pull the switch out enough that you can test it with any kind of tester this is just a basic voltage detector okay and sure enough this is off the electricity is not running to this use one of these guys if you can okay the next thing that you want to do is take a picture of the electrical wiring in my electrical box I've got two cables coming into it one cable has a black red white and bare copper wire the second cable just has your standard white black bare copper wire white is traditionally neutral black is traditionally hot bare copper is traditionally ground so the basic setup of our electrical box is this you have your two neutral wires pigtail together you can set that aside you've got your two bare copper ground wires pigtail together set those aside this red wire and black wire belonged to the same electrical cable okay but what they did here is this black wire belongs to the second electrical cable entering the box this black wire what they did is they stripped three quarters of an inch of insulation off of it wrap it around the terminal screw of the switch and then ran it back and pigtailed it with the black wire that's cuts partners with this red wire you can do that but I prefer to just go ahead and cut this wire this wire here that's not partners with the red wire pigtail the two black wires together with a third a third black wire and then wrap that around what they should have done is wrap that around the second terminal so I'm going to show you how to use this wiring configuration to wire up your motion sensor or occupancy switch if you can't remove one of the wires because they fed it into the back of the switch just go ahead and cut it and then you can strip it whoops okay so there you go this red wire and this black wire belong together they're brother and sister the next thing that I'm gonna do is remove this black wire that goes to the two that will the three wire cable that enters the box okay the way that the electricians wired this it's acceptable but my electrician excuse me electrician prefers to not do this it takes a lot of time to strip insulation in the middle of a wire run you're better to just pigtail the wires together so what I'm gonna do is go ahead and cut this like so all right and if you want to you can just make sure that you have about 300 if if you have any necks or any wire that looks bad just go ahead and cut this off and strip it three-quarters of an inch but this wire looks pretty good this one is a little bit mangled so what I'm gonna do is cut this all right and then I'll strip it three-quarters of an inch so what I'm gonna do now is I'm gonna put these together okay I'm going to use this little piece of wire what I'm gonna do is I should have a bit of a a bigger wire but I'm gonna show you here what the deal you want to put all of these black wires together like so okay you can have them all like this and make sure that you use the appropriately sized wire nut all right so have pigtailed all these black wires all these hot wires together alright I have this one black wire coming out and it's gonna be connected to the motion sensor switch alright I'll show you how to do that next so again you have all you both the black wires pigtailed together you have a separate piece of insulated wire coming out of this pigtail this separate piece of wire is going to be connected to one of the black wires of the occupancy switch or motion sensor switch this other red wire in my case is going to be also connected to the other black wire of the occupancy switch so the cool thing about the the Lutron occupancy sensor is that it will work with all Bob types okay and has an occupancy in a vacancy mode the vacancy mode allows you to actually turn the switch on and it will turn itself off the occupancy switch the occupancy mode that is will turn the light on when you enter the room and turn itself off when you leave the room okay so that's what's cool about the maestro occupancy sensor switch the other thing is this is for either a single pull or a three-way switch okay so what that means is that it's gonna come with - excuse me two black wires a ground wire basically two ground wires and a blue switch because this is a single pole because this is a single pole switch or wiring that I'm working with I don't need to really worry about the blue wire I can just cap that so what I'm gonna do here is I'm gonna wire the two the first black wire from the occupancy switch up to the red wire okay let's do that right now and you get these wire nuts these yellow wire nuts with the occupancy switch alright so there's one and then what I'm gonna do here is wire what not the green one I'm gonna wire the other black wire that's coming from the occupancy switch up to the black wire that I take tailed okay alright so here you go put these two together okay and then what you have is this green ground wire and this other bare wire coming from the occupancy switch I'm going to add them to the existing ground wires okay so I'm going to add the green wire and the bare wire here that came with the occupancy switch to the two ground wires that are entering the electrical box so we're gonna add a wire nut here alright and then you can cap this blue wire because you don't need it you don't need this blue wire when you're using a single pull switch when you just have a single pull switch alright alright so what you do is you should have all these wires back into the electrical box hopefully your electrical box is big enough okay so shove the neutrals to the back of the box shove the ground wires to the back of the box alright I'm going to shove the pots to the back of the box and the blue wire that's connected to the occupancy switch and really it's just that simple alright so now just make sure you have enough room in the box to attach the occupancy switch to the wall there is an up arrow so that you know that it's facing the right way
