    Depends on if you want to be able to dim them from a single location or dim them at all.

    I install individual xenon with the transformer in each unit that has a hi/lo switch. No dimming.

    I went with LED
    3 pull around 4w total, 1 transformer can power up to 6 puck lights
    Each puck light has 12 LED's - lots of light - no heat

    I got some inline LED strip lights. A 15" with 21 leds (I think) fits perfectly under the cabinet. They are powered by 110, no transformer. Not dimmable but at about 1 watt per strip we can leave them on forever.

    We used these for years but the price of oil keeps going up and we may go back to dipping strings into wax again.

    If I choose to go with low Voltage… What is the best install procedure? I want them switched so should I

    Countertop switch to an outlet on top of cabinets to power a transformer.

    If you do choose low voltage, none of the wiring can be concealed in the walls. Makes for a tough clean looking install.

    I don't know that this is entirely correct. As long as the wiring is rated for it you can run it in the wall, yes? What if you used 14/2 romex between the xenon fixtures and transformers. Or what if you used 14 gauge in wall speaker wire?

    Uh, Mike? They're DIYers. I doubt they have a copy of the NEC kicking around. Could you maybe explain, briefly, what's meant by "Chapter 3", "Class 2 power source", and "725.130"?

    and 725.130 refers you to 8 other code sections :rolleyes:
    Chapter 3 is probably a hundred pages or more

    Well then why are they installing electrical circuits for if they don't have a copy of the rules?

    I have been doing this for over 40 years and I got to have a copy of the rules to know if it is right or wrong. Are they that much smarter than a old seasoned pro like me?

    I suppose that it would be a lot simpler to just go make the installation for them than to try and teach the NEC on a discussion forum but I will give it a go anyhow.

    Chapter Three of the NEC is titled;
    Chapter 3 Wiring Methods and Materials

    This chapter will contain the rules that apply to the wiring methods of all conductors, cables and raceways.
    The referral to chapter three in 411.4 means that any of the wiring methods out there and approved for branch circuits would be allowed to be used.

    A class 2 circuit is one that is supplied by a class 2 power source and the rules change. They can’t be around circuits that are bigger than they are as they might get hurt. There are about a half dozen conductors listed for the installation of class 2 power limited conductors. Speaker wires are not part of this listing.


    I feel as though I must ask you a couple of questions now.
    Do you really think that someone would undertake installing something that is sure to cause fires and kill without first doing a lot of research on the proper safety issues?
    Surly you don’t think that someone would undertake an electrical installation without first obtaining a copy of the current electrical codes and doing an in-depth study of said codes, do you?

    The whole idea of forums like this is to assist people

    Do I think people should undertake wiring without research?
    NO, but that IS what the person is doing

    Do I think people will undertake wiring without research?
    YES, especially when they receive "assistance" such as yours

    You might as well have said: "The answer is on the internet somewhere, go find it"

    A better answer would be:

    NO, you can't do that see - code such & such
    or
    YES, you can do that as long as you follow code such & such

    AND giving them a link to look up the code, like this:

    http://nfpaweb3.gvpi.net/rrserver/browser?title=/NFPASTD/7008SB

    That is how people learn
    Otherwise they will just ignore code & do what they want
    Which is what everyone does NOT want, including the person looking for help

    I understand that you have no way of knowing but I have been dealing with Frenchie for about as many years as you have been walking and the post was really meant as a joke that only me and Frenchie would understand.

    But I do thank you for responding.

    Well, when I said it was on the net, I said it, because it really is. I looked it up. So, the poster would be able to check it out, too, and see for himself what the classes and codes are, not all that difficult to do. Or even read. They are capable of doing that.
