Take a hint from how power company electricians approach (literally) this situation: if you think you're very sure that the power is off, then there should be no danger from attaching[2] a (higher rated [1]) grounded conductor to the circuit in question [3]. [1] The ground "strap" must be of higher rated amperage than the (circuit breakers, conductor ...

RedGrittyBrick has an excellent description of tools. I would like to add some more to the topic of procedures. Whichever tool you choose, use it in the way that gives the most assurances that the result is accurate, and then still act as though the circuit is hot. Test with the power on to verify that your tool is working. Test with the power off to ...

Test Tools Voltage tester A professional electrician would very likely have one of these: If you expect to do occasional electrical work in the rest of your life, you should consider buying something like this. It does not make you part of the circuit. It has no knobs or switches that can accidentally be left in the wrong position. It has no removable ...

Before the home was built, there should have been site and soil surveys done. The builder use the results of this surveys, to determine how to properly construct the foundation for the building. Assuming these surveys were done, and the engineer designed an appropriate foundation. There should be no danger to the structure. However, if the water was not ...

What kind of soil is there? Clay could be a problem as it turns to jello from vibration. Good gravel that drains well may be OK. Ask an engineer would be best.

Actually if you look closely, I think that I can see one potential issue. The hose might be crimped; you should check that and maybe pull the dryer away from the wall.

Do I have anything to worry about? No. The air coming out of the dryer vent is not hot enough to ignite anything. Otherwise they would require a double walled vent pipe. Try putting your hand on the pipe while it is running. You will see it doesn't really get very hot. Good luck!

I've worked around power lines for years as well as other people in this thread. I always plan my work around the power company disconnecting. They are mostly accommodating with scheduling and I have never been charged. If they did charge, I would completely be ok with it. Better safe than sorry. I'm not in a hurry when I'm trying to do a job safe and right ...

There are splices rated for being closed up behind a wall without a junction box. http://www.homedepot.com/p/Tyco-Electronics-Romex-Splice-Kit-2-Wire-1-Clam-CPGI-1116377-2/202204326

Junctions and terminations must be in a box, and the box must be accessible. You can't bury it under a floor. Unless you have an idea where the source is, you'll need to treat the wires as though they're live.

It's not a problem. Your septic tank should be full enclosed and the vent/access pipes should be sealed. It's unlikely that roots from small shrubs will make their way in and cause clogs.

Lots of over-thinking for your solution. Glass: Talk to your local window retailer about installing a shatter-resistant film on the glass. 3M and BurglarGARD films can prevent an intruder from breaking out the glass easily. Proper installation is a must. It's not as easy as adding window tint film. And an FYI: modern tempered glass for residential windows ...

Try a magnet - dollars to doughnuts, those are somewhat peeled and rusted chrome plated steel, and the blue is a normal steel oxidation color, and not toxic (also, were you planning to drip food down there, scrape it off and then eat it? If not, nothing to worry about regardless.) They are stunningly unlikely to be copper, though there may be a minuscule ...

Edit3: Bleach will react with copper to produce copper hydroxychloride and as wikipedia says, is commonly found in metal corrosion products. Iron (II) chloride is often greenish colored. Iron and copper chloride will react to produce iron chloride. Looks like bornite (Cu5FeS4) (yes, bornite is toxic too). But it's unlikley, unless someone spilled some ...

I'm a little skeptical because of how purple those stains are, but if these drip pans are made of copper then it could well be Verdigris. This is likely happening because the plates were not sealed properly and vegetable oil was spilled and not cleaned off as heat was applied over time. If I were you I'd scrape some off (it's OK if some powder comes into ...

I've come across a scenario in which this feature might actually improve safety: Some older European buildings still have TN-C wiring in place. Current wiring codes no longer allow this due to safety concerns (which I'll get to in a minute), but there is no requirement to upgrade as long as no modifications are made (simple replacements, such as installing ...

If I plug the 2 chargers and fully utilize them (connect all ports to charging iPads), am I overloading the socket? No. Which one is the correct interpretation? Neither. The step down converter trades off voltage for current but it's not perfectly efficient and it's input won't have a unity power factor. Furthermore under some loading conditions ...
