12 gauge vs 14 gauge house wiring
Comments (15)"My main point is that you don't know what is going to be plugged into any outlet. I just don't see running #14 anywhere that will include an outlet. " I get your point, but I disagree. "I like for my lights not to dim when someone runs a hairdryer in their bedroom or runs the vacuum. " My own home is wired with all #12. I STILL sometimes get dimming when an A/C or the refer kick on. After doing this work for over 25 years I know this can be a normal occurrence. "And the carpet cleaner isn't continuous, but it does put you just a few amps away from your rated load. " So??? " In my own home, I may plug the saw or air compressor into any outlet - depending on where I'm working. " OK, but this is an extremely rare thing, and even then, I have been on MANY a job where this is happening with NO ill effects other than maybe the odd tripped breaker due to running two heavy loads simultaneously. "Yes, I've seen lots of overheated connections on lighter gauge wiring - particularly when someone is using a space heater. I see it mostly when the push in connections are used on outlets. " This is the the fault of the connection, NOT the wire size. Fact....See MoreElectric wire installation,using a smaller gauge wire for the ret
Comments (3)I don't know where you heard it but that is not true. The current carrying conductors must be the same size. What you might be misunderstanding that in some cases the EQUIPMENT GROUNDING conductor (i.e., the safety ground not the return from the motor) can be a smaller size. For 15 and 20A circuits however, it still has to be 14 and 12G respectively. It's only when you get up to larger sized circuits that it is possible that it is legally smaller. The number of pumps you can put on a circuit is not regulated. It's determined by the load (amps drawn/size of the motors) and the nature of their operation. etc... You'll need to give us much more description as to what you're trying to do to give an answer on that one....See MoreMost complicated under counter plugmold in the world? (pics!)
Comments (21)akchicago: I did look at the pre-made angled plugmold, but a few reasons prevented me from using it. 1. very expensive 2. did not want the brushed nickel finish, prefer the anodized aluminum look to match my tambour doors and toe kick. 3. I had two miter cuts to deal with and needed blank raceway over the sink, so really using the pre-made product didn't give me the options to fully integrate it since it is not meant to be cut and does not come with other parts needed. andreak100: Regarding the LED strips, I used Philips Color Kinetics eW Profile Powercore LED strips. I used several different length sticks to make two contiguous runs separated by a small connecting cable to make a 45-degree turn. These were purchased from Farralane lighting, & audio inc., online, which had a pretty good price if you register for the website. I purchased the "Gray" housing which is metal and really looks almost like anodized silver aluminum (but the plastic parts are gray). The LEDs are covered by a diffusing lens, which I think helps spread the light around uniformly. Note that they mount toward the front edge of the cabinet, not in the back, and they light both the coutntertop and backsplash, pointing away from the user. I liked this better than some LED options that seem to point only down or only back. These come in three different color temperatures, I elected the middle option of 3000K, and I think they look nice color wise, but I have not seen the other options to know how they compare. These LED bars use 120v, and because of this required no hidden transformer. There is an in-line switch and wiring box option that I used to clip directly on to the end of the LED bars. Very integrated looking and you can turn them off and on by flipping the switch right there under the cabinets. Note that I did ALSO install an in-line 120v switch in the lower cabinets with the intent of using a dimmer with these, since they are dim-able. The idea was to keep the dimmer set at the desired light level and turn it off and on daily using the under cabinet switch. However, I went through a few dimmers trying to find one that worked well with it (and eliminated buzzing), but was never very happy with that. Therefore, I removed the dimmer and just put a switch in-line (or I could have hard wired them to be always on I suppose but I didn't have the right coverplate). Overall, I am very happy with the LEDs. I am also installing one of these in the Appliance Kiosk underneath the bottom shelf to light the work surface (the toaster oven is mounted above the counter and blocks the overhead lighting), and the LEDs will turn on with the same switch as the overhead recessed light. I'll post more about the Appliance Kiosk soon!...See MoreOld 12 gage wire and new 12 gage wire
Comments (16)What you are missing is that if there is no ground wire in the existing cable, there will be no ground for the circuit and any extension of that circuit. The new cable's ground wire can therefore be ignored because if it were connected it would not be doing anything. Connecting it would only mislead someone who was working on the circuit later. The purpose of the ground wire is to trip the breaker if the housing of the exhaust fan came in contact with the wiring and would shock someone who touched it. It is unlikely that someone would be touching the housing unless there is a light in the fan housing. I'm not sure what the electrical code says about extending a non-conforming circuit to a new fan but I doubt it is allowed. Of course, it is also likely that only a licensed electrician is allowed to do this work. In any case, if the installation caused a fire it is unlikely you would be insured if there was evidence the fan was not installed by a previous owner. Also, if the new junction box is metal you must use cable clamps where the cables enter through the knock-out holes. The box not only provides isolation of the connection but secures it so it can't be pulled apart. The cable must also be stapled to the framing at certain intervals; it can't be lying loose in the attic. 2 wire ungrounded non-metallic sheathed cable is rare in my area. Post knob & tube, home wiring was metal armored (AKA "BX") and the metal provided a ground to the metal boxes although it was not always reliable for long circuits. In the 60's an aluminum strip was added inside the cable to improve the continuity of the ground. Non-metallic (plastic) sheathed cable (AKA "Romex") became popular in the 50's and in 62 the electrical code made a bare ground wire mandatory for all branch circuits. For your wiring to have only 2 wires and no ground it would probably have been installed in the 50's by someone who didn't want to use BX cable. But this is not all bad because the insulation on BX wiring tended to crumble when exposed to air and is more dangerous than any other kind of wiring wiring. For any further help you should post photos of the original cable and the main panel with the cover off. Tripping the main breaker is wise but NEVER assume a branch circuit is dead without using a voltage detector. If a breaker can be turned off, it can be turned on again by someone else. Always put a note on the panel. A 120v wire can stop your heart instantly. A voltage detector is the smartest $10 you will ever spend.
