I am a software programmer using C#, C+, and (less often) PHP. I frequently work with SQL, HTML, CSS, Javascript, and XML.

I own a business for technical consulting, programming, general IT work, and designing custom electronics (usually for costumes and theater/movie prop use).

I enjoy computers, music composition, photography, writing, sci-fi/fantasy, birding, and occasional cooking. (Many of which are topics of SE sites!)

A note on capitalization, spelling, and grammar: I care about the quality and readability of the questions and answers on StackExchange sites. I frequently edit for these reasons. I understand that not everyone knows English as their first language. If I leave a comment for you asking you to observe some language-usage convention, it's meant as a helpful hint, not as an attack.

comment What gauge wire/cord do I need for these outdoor lamps?
@Speedy I didn't say insulation does not matter, I said it doesn't change how much current a given wire can carry. The more current a wire carries, the higher the temperature will be, and thus you need to have an appropriate type of insulation. Different charts provide "safe" ampacities based on ambient temperature and insulation material. Yes, I have seen (and worked with) NEC information. What terms do you find erroneous or not standard?

comment Are extension cords safe for permanent use?
I would add to this list to never use an extension cord when still coiled up. The rating assumes the cord will cool in open air, but coiled-up cords cannot dissipate heat very well, which can lead to a fire.

(I should have added that the voltage drop was at the ~5.7A load of the lamp. It would be more with a higher wattage load.)

Also for a more general guide to selecting extension cords, Home Depot has a friendly chart without all the math. :) (Though it is a bit less conservative.) General Cable also has a PDF guide.

comment What gauge wire/cord do I need for these outdoor lamps?
The ampacities given by NEC are less conservative than the table I used. For 10 AWG copper wire with a 60°C rating, the value given is 30 A (compared to 15 A). There are many factors involved, but I would hesitate to use a 10 AWG extension cord for a 30 A load. Also, I calculated the voltage drop for a 100' length of 14 AWG extension cord (200' total) to be < 3V, which I wouldn't necessarily deem excessive.

@Speedy A lot of ampacity charts show values like the one I linked. "Chassis wiring" is meant for wiring in air, while "power transmission" is for wiring in bundles (ref), as you would find in a typical extension cord. Insulation type doesn't change how much current a given wire can carry directly, but matters because a wire carrying high currents at high temperature can burn or melt insulation that isn't rated for it.

comment Why is high voltage coming out of HDMI port on my TV?
This question appears to be off-topic because it is about a home electrical problem that should be addressed by an electrician on site.

comment Live wire touching ground, sends power back through TV cable
Unfortunately this question isn't really on-topic, as it's not about electronics design. I think you just need to find a reputable, qualified electrician to come and sort out the issues. There's no way to provide a reasonable answer in the context of this site, as nobody here has access to your household wiring to perform some basic measurements and inspection.

You have this backwards; see the skin effect.

Cinder blocks, no matter the orientation, would raise a bed more than a "few inches."

comment What is the purpose of the “grounding” tab/wire on a 3-prong to 2-prong adapter?
@Brad 1. Research if the manufacturer still exists and if so, if the company is wealthy. 2. Ensure you have purchase receipts, warranty registration card filled out, etc. 3. Operate some machinery using the adapter, perhaps something that doesn't have safe wiring (wink, wink). 4. Sue for damages and profit.

One of the great things about SE sites is that you can ask a question (even if you know the answer) because you want to either a) answer it yourself as a reference for others, b) get additional answers to elaborate and expand on something, or c) you just want to get more internet points!

comment What are the pros/cons of different wire connectors on a switch/outlet? OR How can push-in wire connections fail?
@BlueRaja I was making a joke about the underlying reason. I agree with you, the "screw wrap" is the most proven and reliable.

Electricians prefer the "screw wrap" method because it gives them a reason to use those little holes on the sides of wire strippers. :)

The single thermostat is in the hallway, between the rooms with vents. I'll add this detail to the question.

comment How can I avoid cold rooms due to combustion air intake?
Water heater is gas, and right next to furnace, so those could be enclosed together. Clothes dryer is electric. Gas range (upstairs) I wouldn't think relies on a combustion air that's so far away?

comment What to look for in a new/replacement toilet?
If the cheaper ones do a good job, but are flimsy, then I'm ok spending another 50 or 100% to get one that's sturdy also.
