Running a window/wall unit AC. Does 5 degrees in temp equate to much more money spent?
Q. Hi. My apartment has a window-style AC that is built into the wall. I know these things aren't cheap but I'm wondering how much of a difference there is between having it on, say, 75 F or 70 F. Any help from you electrical whiz kids would be great!
A. That 5 degrees is gonna cost you about 20% more between 75 & 70F. I compromise in our bedroom, I run the energy saver set at 75F during the day, and then drop the temp about 2 degrees and take it off energy saver at night when I'm sleeping. The a/c unit turns itself off on energy saver and the starting and stopping wakes me at night. I'd rather have the constant hum of the fan. The rest of the a/c units (two smaller ones in the downstairs) are set about 75F, much to husbands distress. He would prefer to have it like a meat locker but not on my budget.
how many plugs per breaker on average if unknown what will be on it?
Q. rewiring an old house that had no ground and EVERYTHING was on like 3 breakers.
A. ok, when I wire a residential home, I wire lights and receptacles together on 15 amp circuits, usually counting each outlet or standard light as one device, and putting no more than 16 devices on one circuit. Now if you have a lot of lights, then you would add up wattage and figure 1440 watts on a 15 amp circuit.
Now commonly I wire two kids bedrooms together on one circuit and the master bedroom by itself, unless there will be a left over bedroom also on it's own circuit.
NEC 2005 says all bedrooms need to be on arc fault circuits.
(special breaker)
Also most counties require 120 volt smoke detectors inter-linked in every bedroom and on each floor within 10 feet of the stair landing.
Living room might have its own circuit because of entertainment equipment. Dining room should have a dedicated 20 amp circuit to plugs. Kitchen requires two dedicated appliance circuits 20 amps and protected by GFCI at any countertop receptacle, or if any receptacle is within 6 feet of a water source. (Gfci's are only needed at the start of the circuit, and following receptacles can be protected by it)
Bathrooms require a dedicated 20 amp GFCI circuit. All bathrooms can share one circuit.
Standard wall spacing is every 12 feet along perimeter of wall and within 6 feet of any door or break in the wall.
Any wall 16" or bigger requires at least one receptacle.
Railings, knee-walls, and even kitchen cabinet peninsulas are considered wall space. Also the inactive panels of sliding or double doors count as wall space.
Also Countertops in kitchen area have special spacing requirements. Within 2 feet of any edge or break of the usable counter, and every 4 feet maximum. Any countertop 16" or wider requires a receptacle.
Islands and peninsulas require outlets on the sides within 6 inches from the bottom of the counter. Also there can't be an overhang more than 3" over that receptacle.
Dedicated circuits are needed for dishwashers, disposals, hoodfans, built in microwaves, stoves, ovens, heaters... Gas powered appliances can share 15 amp circuit for controls.
inspectors usually check the name plate of an appliance for proper wire size and breaker.
Inspectors also require a disconnecting means for any large appliance not in the kitchen, like a water heater or furnace, or outside A/c unit, if not within plain sight of the panel box.
there should be a GFCI protected outlet within 25 feet of any outside appliance, and within 6 feet of the front and back doors. In certain cities, you have to switch the front receptacle to prevent people from stealing power from you.
3 way (and 4 way) switches are needed when a larger room has two or more entrances, also at the top and bottom of any stairwell with more than 6 risers.
Every room must have a means of switching a light at the entrance, being either a light or a switched receptacle (half-switched is acceptable)
Wire should be staples within 12 inches of a box and every 3 feet unless traveling vertically through studs, or over ceiling joists in a perpendicular manner.
Standard receptacle height is 16 inches to center AFF
Switches are 46 or 48 to center AFF
Counter top devices are usually 48 to center.
There's probably more you need to know, but I don't even know what the extent of your project is, or if it is even being inspected.

What do I do a tornado is headed to were I live?
Q. I no they say go to an interior room but I have none the only thing that is a closet that has our centrale air and heat unit in it the closets in both bedrooms r on a outside wall Im scared and I have a 15mnth old daughter an three dogs my husbands at work an we only have one car an family lives out of town pls some tell me what to do
A. First things first: Do NOT panic. You're the adult, and you need to stay level-headed for the sake of everyone else.
Second thing: Bring the dogs inside to a small room, and grab a pillow or two. Go to the closet with the central air and heat with your daughter and stay huddled down with the pillow covering your head, while holding your kid. If your dogs are small, let them come in as well.
Tornadoes are not as frequently destructive as weathermen may make you think. Frequently very little damage will be wrought by one, with little to no personal injury. Wait until absolutely necessary (sirens blaring, and really loud wind) to take shelter. Tornadoes pass by very quickly, so you may only need to take shelter for 5~10 minutes, max.
Also, if you're religious (or even if you're not), pray. It helps you feel a lot less alone in a weather crisis.
