comment How can I add a circuit breaker when there are no openings available in the neutral bus bar?
@SteveFallows I sometimes use the wrong words, and this is the case here. It is indeed true that you will often see two wires under a screw, but nine times out of ten, it is a violation. You are only allowed to put an extra wire under the screw if the part is UL-listed for that purpose.

comment Calculate savings from/cost-effectiveness of installing a tankless hot water heater?
If you assume $1/month in savings, how long is it going to take to pay off the extra $200 (best-case scenario)? 16 years. If you have to buy a water softener, upgrade the circuit/breaker, and/or upgrade your entire service, it's going to get ugly very fast. Of course, if you live in an NYC apartment/condo, it may be worth it to spend an extra $200-2k just to free up some space, but that's a special case and those who live in a tiny apartment/condo are very space-conscious and aware that they have to conduct a very different cost/benefit analysis. (Some will also value the novelty.)

Of course, salt-based water softening has its costs, and if you don't have it, you'll have to spend several hundred dollars acquiring it. That $2.20/mo. savings is quickly eroded and, over time, even reversed. On top of that, they are massive amp draws, often requiring upgrades to the circuit and/or service. Massive amp draws also wreak havoc on the electrical grid (sharp changes in electrical demand cost electric companies money; TXU is right now offering 100% free electricity at night to mitigate their daytime "peaks"), and the electrical companies pass the costs on to their customers.

@gregmac Electric tanks lose very little heat, and the only thing that tankless eliminates is standby losses. This comes out to about $2.20/month. They are less efficient in their generation of hot water, however, since tanked water heater elements are surrounded by several inches of water and insulation, and since, upon shutdown, the vast majority of heat built up within the tankless' heat exchanger will be lost to the surrounding air. They also scale up much quicker, so their efficiency will take a further blow unless you have salt-based water softening.

comment How do I choose a circular saw?
Yep. For those willing to spend the money, Milwaukee and Makita are the best tools out there right now. This generalization is true almost across the board. One notable exception is rotary hammers, where Hilti is the best. Milwaukee = a little more power; Makita = a little more finesse (very lightweight tools, reduce fatigue, etc.) Other brands (DeWalt, Skil, et al.) make perfectly acceptable circular saws, though. Nothing wrong with cordless, but you are making a bit of a tradeoff. Little less power for increased mobility. At times, that extra mobility can be a blessing.

comment Why does voltage still exists when a circuit is broken by a 3-way switch?
@Tester101 It turns off completely, but it has had a CFL in it for quite some time, which may require a certain voltage to light up. However, it also turned off completely back when it had an incandescent in it.

Also, I am merely updating an existing installation. I could draw how I think it is wired (your typical three-way installation), but I don't know if anything else exists behind the walls and in the attic, such as a jbox.

@shirlock homes The voltage is present almost everywhere. As soon as I hook-up the travellers, one will read 123V and the other 37V or 55V (to both GND and neutral) depending on which is disconnected. This continues on to the luminaire itself, which has voltage (to both GND and neutral) even when turned off. The neutral is unbroken at all times.
