I want to install about 12 step lights that will be 12 volt

Hello, My name is ***** ***** I want to install about 12 step lights that will be 12 volt on a retaining wall using two transformers,one string of lights will have 5 lights at a distance of about 24 meters from the transformer and the other string of lights will have 7 lights and a distance of about 17 meters but my question is what sort of cable should I use so not to get voltage drop. Also can I wire the transformer plug into a switch so I can just turn on a switch that turns all lights on at once. I live in Australia and not sure what rules and regulations are for installing 12 volt lights without an electrician. Thanks for your time. Tim

Tried wiring a temperature controller for a fermentation

Tried wiring a temperature controller for a fermentation chamber, following this diagram: https://s3-us-west-2.amazonaws.com/homebrewassoc/wp-content/uploads/2016/04/temp_schematic1.jpgWhen I forgot to break the tab on the two-screw side of the outlet, everything worked fine but I couldn't control the plugs individually (both were powered). Once I did break the tab, I blew a fuse in my breaker box in my apartment as soon as I plugged it in. Rinsed and repeated with a second outlet, same thing--worked great without breaking the tab, blew a fuse. Every set of instructions online says to snap the tab... what am I doing wrong? No other appliances are running on that circuit that I can find.

I bought a house that has a gazebo about 50 feet from the

I bought a house that has a gazebo about 50 feet from the main home. There are two outlets and two fans in the gazebo. An underground run of 12/2 outdoor NM wire goes from the gazebo to the basement. On the inside, the wire enters the basement and ends in a 2 prong plug. It is not in conduit or hard-wired. There is no ground wire. Home was built in the 1990s and all other outlets are grounded.1. Is the lack of a ground at the gazebo a danger to my family if we plug in the 12/2?2. If yes, is my only option to replace the 12/2 with 12/3 and hard-wire with ground? Or, can I install a grounding rod at the gazebo and wire it to the gazebo circuit?

I started having problems with losing power to the bathroom

I started having problems with losing power to the bathroom and half of a connecting bedroom. The power would restore in about 30 minutes. I changed the outlet but noticed burnt wires.Now other outlets in different rooms are losing power but restoring later. My stove currently has lights/clock but won't heat. I've started checking everything with a multimeter which results in normal reading. Fuses are all good, 120 reading on the outlets. However, the back of the stove readings are 120,105,240. I'm thinking the bathroom wires are the problem but would that cause problems in the kitchen that's not connected as well?JA: I'll do all I can to help. How long have you been dealing with this?Customer: About a year with the bathroom, after I changed the outlet the problems mostly stopped til recently. My wife stopped using the adapter to plug in multiple things: hair dryer, curling iron...kitchen just recently startedJA: Do you plan on doing the work yourself?Customer: I'm not sureJA: Anything else we should know to help you best?Customer: It's an old fuse box, probably 1957 not a breaker

Having trouble replacing a bad motion sensing light switch

Having trouble replacing a bad motion sensing light switch in my home laundry room with a normal toggle switch. Light would not come on so after replacing several bulbs decided to replace the old (Seldon Used Motion sensing switch) I verified the bulb is good by testing in a working lamp. Coming into the light switch box are 3 sets of 3 wires. GROUND: The 3 bare ground wires are wraped together with a wire nut on the end. WHITE: The 3 white wires are tied together with a wire nut. BLACK: Confusing wiring. 2 of the black wires are tied together with a wire nut together with a 3rd short ~4" Back wire extension.(I think so that it is easier to connect it up to the switch? SO 2 wires basically become one wire. The 3rd Black wire coming into the switch box is by itself and looks like it is ready to attach to the switch. (Unfortunately I did not take any pics when I removed the old 3 wire motion sensing light.When I connect the 2 black wires to the single black wire the light does not come on. Also when connecting them to the switch it does not come on. I tested the toggle switch on and off with the continuity tester mode on my meter and the switch is good.VOLTAGES MEASURED:1) 3 Bundled Bare Ground wires to 3 Bundles White Wires = 15V2) 3 Bundled Bare Ground to 2 Bundle Black Wires = 120V3) 3 Bundled Bare Ground to single black wire = 15V4) 2 Black Wires to 3 Bundled White Wires = 65V5) 2 Black Wires to 1 Black wire = 65 V6) 3 Bundle White Wires to single black wire = 0VNOTE. The Electrical outletts in the laundry room(2) also do not seem to be working right. I measure 65V across the 2 slots that should be 120. But I do measure 125V between the Ground pin hole at the bottom and the Right Side slot It seems that they did work last time we tried to use them for the iron.Q1: is there a fix I can make in the switch box that will fix the light and the outlets so they all have 120V accross them?Q2: Should I be concerned that between the ground and one of the wires is 120V. Or will that get fixed when I fix the light switch box.Q3: DO I need an electrician to fix this or can you talk me thru or describe what I need to do to fix this?
