comment Can I safely use a 9w LED bulb in place of a 40w incandescent?
The problem is that lightbulbs used to be measured in popular parlance by wattage (energy), not by light output (lumens) So people went shopping for a 100W bulb not knowing how much light output they were looking for. Since nowadays we have CFL and LED lamps that produce the same amount of light on much less wattage, they helpfully tell you what the equivalence is for the light, in this case a 9W using (energy) will produce the same amount of light as a 75W conventional bulb
comment Can a power inverter work continuosly?
Well, short explanation, you're not going to get 1000W @ 110V by putting in any sane amont of 12V. Let's make up 1100W @ 110V, which give us 10 amps exactly. A typical 1000 watt hair dryer (the amount of heat made) at 12V would require > 80 amps of power to get put into this inverter, probably setting it on fire. What piece of equipment exactly is it that you're looking at operating in this manner?
comment All outlets on one 15-amp circuit, need AC unit… has a gauge/distance/max amperage grid chart. A word of note, a 10 gauge extension cord will be heavy (and not cheap, either)
comment All outlets on one 15-amp circuit, need AC unit
Why can't you use an extension cord? If the gauge is enough it will be electrically "safe" (obviously would still be a trip hazard, suspect to damage, etc)
comment Is this tile installed correctly?
speaking pedantically, did you want a 6" offset or a (random look)? Those are almost opposite words and I can empathize with the installer not doing what you wanted, since I'm not sure what you mean either. They should have asked you before they started and you should have been more precise (diagrams are great!).
comment Is it acceptable to not have access to the main water shutoff valve?
I would install a shut off of your own. It may be an added expense and possibly 'should' be borne by the HOA, but I can't imagine it being more than $500 and the peace of mind it will give you is much more than that.
comment Need a water sensor/switch for basement that I can interface to a PC
If you want to make it even more bare bones you'll need to move to something like Arduino or Spark -
comment Will this light fixture wiring pass inspection?
Doing it the second way has the downside that the fixture is always hot - I.e. you couldn't easily remove a broken lightbulb without turning off the breaker whereas the code compliant way allows you to remove all "hotness" from the fixture by turning off the switch.
comment How to buy a land and build a cottage in the United States?
I think at a minimum it would need to be zoned by the appropriate zoning authority for the purpose you intend. This is probably very state specific. I'd probably give one of the state's new construction licensing/inspection departments a call and ask them - they probably will be able to point you in the right direction.
comment Running air handler condensate drain into sump?
The problem is that in order to get to the laundry sink it has to go across the shelves. I don't have a lot of vertical drop to play with. However, we're going to do the closet track system, and it occurs to me that we might be able to put the vertical standards against the wall, and then just put the PVC across the standards right in front of them, with possibly a couple of elbows to just make sure that we don't bend it too much.

I am in Maryland
comment What could be causing my electric hob to leak voltage?
For those trying to follow along at home, a hob is a cooktop.
comment The best kind of tiles for using on floor and walls
I'm not completely sure what your question is. Are you asking what are the most durable choices for floor and walls for tiles?
comment Can using two hoses deliver more water?
Also, depending on how often you'll be doing this, note that your water bills are actually a water bill + sewage bill in one. The sewage bill is actually much higher, and if this water won't ever get to the sewage it might be possible to rent a hydrant meter. e.g. :
comment What are the differences between these types of small-dimension lumber?
Nobody should ever use furring strips in any sort of structural capacity, they're just meant as a surface to create points to attach other structural members.
comment Can I put a 75 watt equivalent led bulb in a fixture that says 60 watts max?
Possible duplicate of…
comment What is the typical dishwasher/disposer electrical connection?
To be fair, 220/240 in the US can be a mismash but dishwashers fall in the 'standard appliance' category.
comment How do I stop my garage door from opening on its own?
That instructables URL is interesting, but that particular one is just controlling the inside-the-house X10 setup to simulate a push on the button, not sending RF to the garage door opener
comment What kind of wood is recommended for replacing kitchen cabinet shelving?
Just bare plywood shelves? Not sealed or anything?
comment Should I use 2' x 2' tiles for a galley kitchen?
This is largely an aesthetic question ,as you point out. It's not great for this site.
