I have a three switch plate next to my front door that

I have a three switch plate next to my front door that operates #1 Interior lights, #2 Entry light, and #3 Porch light. I bought a dusk to dawn light timer that's meant to replace the #3 switch in the bank of switches. However, once I turned off the breaker and opened the light switch housing, I'm totally stumped by the wiring. I should note that this wiring is less than two years old and was installed as part of a remodel project (by a professional electrical contractor). Here's how it looks: There are four white conduits leading to the junction box. Conduit "A" has wires red, black, white, and green. Red is connected to the top of switch #1. Black is connected to the bottom of #1. White is connected to a hub of several other white wires coming from the other 3 conduits and tied together. Green is connected to a hub of all the greens. Conduit "B" has a black wire connected to the bottom of switch #2. White is connected to the white wire hub. Green is connected to the green wire hub. Conduit "C" has black, white, and green wires all connected to their respective colored hubs. Conduit D has a black wire connected to the boom of switch#3. White is connected to the white hub. Green is connected to the green hub. The hub with all the black wires has dark grey wires that connect this hub to the bottom of switches #2, and #3.So this timer switch that i bought to replace switch #3 has red, white, black, and green wires. Switch #3 (like switch #2) has a black wire in from a conduit and a black wire from the hub of black wires. How should i connect the new timer switch into this configuration? That you for your help!

We're installing a heat pump pool heater about 300 feet from

We're installing a heat pump pool heater about 300 feet from our home. The heat pump is 145,000BTU, requires a dedicated 50amp circuit. In addition, we will be running a 1.5HP pool pump and some LED lighting. We'd like to run a sub panel from our home to power all of this. We're planning on running 2 1/2 sch40 conduit from the house to the pool to carry wiring. I'm just not sure if (1) I can do this without too much voltage drop and (2) if I'll have big enough lugs at my main panel to accommodate this.

I bought a top of the line whole house fan. It has a 1/3 hp

I bought a top of the line whole house fan. It has a 1/3 hp motor. I've run 14-3 NM cable to it. Instructions on the fan are not any help. It doesn't have a "box" attached to it to do the wire nut connections, but it does have a plate that you can remove and little compartment under it. Under the plate there are 3 bolt connections (no nuts included) and 3 spade connections with wire attached. Attached wires only extend 6" from motor however.How am I supposed to wire this? It doesn't seem like there a lot of room to tuck these wires in, but there isn't a long pigtail to be able to install another junction box either.

I am replacing all down-hanging light fixtures with recessed

Hi. I am replacing all down-hanging light fixtures with recessed lighting, the kind with the wiring clips...My hall lights are a downstairs and upstairs light connected turn on and off by 4 switches:1. Kitchen2. Bottom of steps directly down hall from kitchen3. Top of steps to second floor, directly below where upstairs fixture is4. Down the hall from 2nd floor switch and lightThe switch down the hall is a bigger/fatter switch--I guess a 3 or 4 way (I have no clue what I am doing here). It only cuts the power from the other switches. We have to constantly leave it in off for the other three to work.Inside of the hole of the old fixture where the new hole for the can is sawed in the downstairs hallway, there was only standard romex 3 way wire (if I'm saying that right--black, white, copper).In the upstairs hall, there is 3 sets of wires:1. 2 sets with Red, Black, White and Copper2. 1 set with Black, White and CopperThe recessed lighting can has the clip in wire receptacle--multiple inlets to chain lighting together.My questions are,1. How do I wire the recessed lighting box?2. How do I connect the 3 sets of wires upstairs?3. What causes the Lightswitch at the end of the upstairs hallway to cut off the power to the other three switches? I have changed out the switch to test it and put a new one in--same issue.

I am installing a ceiling light where a light / extractor fan

I am installing a ceiling light where a light / extractor fan switch used to be. The light and the fan used to have their own adjacent switches. The cable from the mains is just a single three core on the lighting circuit so I take it to be an 'end of loop'I have made alternative arrangements for the fan . It is now fed from a mains power socket.I want to feed the new light fitting from a ceiling rose, with a torpedo on-off switch between the rose and the light. I am confused about how to wire the rose, which is designed for a loop and a remote switch. There are two wiring points marked Live, three marked Loop and three marked Neutral (plus Earth). Which should I use?

My bathroom light fixture went out so i replaced it, i connected

my bathroom light fixture went out so i replaced it, i connected it white on white, black on black, copper on copper. easy, the light works. then i replaced the light switch with a dimmer switch. hard, there are 3 wires coming out and they all look the same ( 3 black wires ). i have a tester so i can tell which one is hot. by trial and error i got the light to work with the dimmer switch. anyway, the next day i noticed that the plug-in no longer works. i do not know at what point it stopped working. with the old switch i can get it to turn the plug on when the switch is off, the plug never has power all the time ( it used to ). if i attach the dimmer switch (red to hot black, green to one cold black and black to the other cold black) the plug never works. i'm very confused as to what could be wrong.here are some pictures of the outlet, wires and light fixture. the orange cap is the hot wire.https://onedrive.live.com/?id=E68E4F3F25B3D822%2153744&cid=E68E4F3F25B3D822
