What does a True RMS meter do for me? My meter is an old Simpson True RMS DMM. I've taken a circuits class and a signals class, so I have a pretty good idea of what RMS means. I guess what I really would want to know is what the "false" RMS meters are doing.

Would a light sensor/motion sensor on the light work for your wife? The light sensor gives the same on at dusk, off at dawn effect, without pulling tons of wire.

Your first post, with the pictures shows your projector rated at 200W. At 240V, that means it draws an amp or so. A 1A fuse will work here. Wikipedia says only 2 (black or blue), 3 (red), 5 (black or grey), 10 (black or yellow), and 13 (brown) amps are commonly found. 2A will work.

Your thermostat can be replaced from the front. If you take the old one off the wall, what does it look like? Also, in my area it's cold enough that I wouldn't want to be without heat. How long can you go without heat (or cooling, if you are in the southern hemisphere) if the new thermostat doesn't work, or you have to do substantial work?

I pay 3.59c/kwh + $4.10/month.  At an old place I had a auto-read meter. It apparently had an internal battery that died, so the last two months I was there were estimated. The LCD display was blank even. I was ready to fight whatever bill they were going to send, but the company's estimates were really low-balled, like half of what I thought we actually used.

Are these any better than leaving a power adapter plugged in all the time? I still lose a plug, and it still sucks down power when not in use. Having two plugs and two usb ports would take care of the first problem, but wont the USB ports get covered up if you have a transformer plug?

asdf32 posted:I have plans to rewire most of my house over time and one thing I'm considering is installing this wire duct in the basement. The main beam in the basement has probably a dozen wires coming and going and going to/from the walls above. I'd love to neaten it up. I've worked on equipment that uses that type of race. When you install the cover, you have to snap in each finger individually, and the fingers like to break off all over the place. Those clips look like a better idea.

poxin posted:So I just got a NEST thermostat and it appears after many hours of tech support that I need a 24v C wire to power the NEST. Using the voltage on the Y/Cool wire is making it drop too low and it shuts the switch off. Problem is I can't find a C terminal/hookup on the control board. Anyone have any ideas? Use the common on the transformer. In the diagram, 24 VAC common is shown on the lower right. This looks like it has the same diagram, if you want to look at a cleaned up version: http://igate.northernplumbing.com/manuals/goodman/pgb.pdf

It's an Edison socket, but only has about one thread. The rest of the inside is unthreaded. Also, it's a pendant light, so I have 3' of slack between the ceiling and the socket. E: Well, with a finer tool, I managed to bend the tab into the right place. Still thinking about replacing it for the satisfaction of throwing the old one away.

A two pole GFCI breaker can work on both Hot-Hot and Hot-Neutral circuits. Think about how a single pole GFCI breaker works. It essentially compares the current out and current in. Now, it isn't really measuring each leg individually. It measures it all together, and ends up with the sum. If the sum is non-zero, indicating a ground fault, the GFCI trips. A two-pole GFCI works the same way. Current can goes out on one hot leg, and either returns on the other hot leg, or on the neutral. The breaker measures the current on both hots and the neutral, and if it is non-zero, the breaker trips.

kid sinister posted:Yeah, but a 2 pole GFCI breaker would have 2 potential hot-neutral circuits. Don't most 240V appliances with 120V features put them all on only one hot leg? Yes, and the breaker does not care.

I have a leak under my kitchen sink, so I was emptying everything out. I noticed that the power for the garbage disposal is just some romex that comes out of a hole in the wall, shared with the PVC drain line. That isn't up to code, is it?

ShadowStalker posted:Yep, they recommend you replace the battery on the battery backup smoke detectors at least once a year. I've let one go for years without replacing the battery to see how long it would be until the battery was low enough where I got the low battery notification (It's a spare bedroom with nothing in it and there's a smoke detector right outside of it in the hallway). The battery lasted 4 years before I started getting the chirping that notifies you that battery replacement is needed. I'd still replace them at least once a year to be safe. What's the point of hard-wired smoke alarms if you still have to replace the battery every year? Or did I misunderstand, and it's a single, central battery?

some texas redneck posted:The battery is there so that the smoke detectors can still function during a power failure. Losing power in a house when it's, you know, I understand the point of having backup power, I just figured that they would use a rechargeable battery, or a supercap. Something that would last more than one year.

I guess what I don't understand is why someone would pay extra for a hard-wired system when they still have to replace the batteries? I understand you get the whole-house alarm, but couldn't a wireless system do the same thing?

Was the room pre-wired for a fan? Someone will probably come in and say how great those things are, but I'm going to say to get a real volt meter. The wires might be too close and the thing you have will alert to either wire when either of them is on.

In my mind, a real volt meter will have two important features:
I haven't shopped for a meter in a while, so I don't know what's out there to give a specific recommendation.

What voltage did your old transformer put out? I guess I'd start by checking the voltage between the Black and White wires (As shown on your diagram) on each bell while the front button is pressed. You'll need a helper. Then I'd disconnect one bell at a time to see if the other works when it's alone on the circuit.

 If the chandelier is on a chain, you could put the box in a more accessible location, and a hook where you want it to hang from. The box won't need to be load-bearing, but the hook will.

Kaf posted:I bought my first home a few weeks ago, and I'm having trouble with the outside front GFCI outlet. (Trying to get some drat Christmas lights working.) Our inspector initially picked up that the existing outlet didn't work, so we had the vendor fix it before closing, along with a few other minor electrical issues. When we did our closing day walkthrough we saw that it had been replaced with a new GFCI so we assumed it would work. Nope. Start by getting a real volt meter (instead of just a detector), and measure the voltage out of that outlet.

I'd suggest using a multimeter to measure the voltage. The best you can hope for with an internet answer is what it is supposed to be, a multimeter will tell you what it actually is.
