There you go. I think what you are looking for is about page 25.

Try www.bsc.ca.gov/, look for part 3 this is the cal electrical code section. If you are working solely in a private residence the NEC 2002 is used for CA. Be sure to check with the local building department and inquuiry about their requirements. If you pulled a permit for the kitchen remodel they would have reviewed the plans and added anything required that was not on the plans.

Hers another link: http://www.energy.ca.gov/title24/residential_manual/res_manual_2001.PDF (See Page 225 of the Residential Manual)

Definately enforcable....

As far as lighting requirements, the big one is in Kitchen and Baths for the first switch in each to be for "general lighting" and Flouresant, or "energy efficiant". See page 95 - 100. (The only other one for residential is that cans in insulation be rated for such...)

Theres a good explaination of what is meant by "general lighting" on page 236-237: http://www.energy.ca.gov/title24/nonresidential_manual/2001_NONRES_MASTER_REVISED.PDF

rlc3854,

We're still on '99 NEC as far as I know, probhably will be for some time. Has a tendancey to lag a few years.

And Plan Check is usually a rubber stamp, as the EC you're still responcable for the work done to be compliant, and subject to the Inspectors X in the right boxes of that type of check list.

rlc3854,
I'll second e57's post.
The 2002 NEC is not in effect in CA., and many, many things are not caught in plan check.

Edward;

In a Nutshell, the T24 Part 6 CEC Residential Lighting regs are as follows:

  • High Efficacy/Efficiency Lighting as "Primary" lighting source in Kitchens - controlled via its own switch(es),
  • High Efficacy/Efficiency Lighting as "Primary" lighting source in Bathrooms - also controlled via its own switch(es),
  • If High Efficacy/Efficiency lighting is used for exterior wall mounted fixtures, then only the Kitchen requires the High Efficency lighting source.


High Efficacy/Efficiency lighting source = Lamps with at least 40 Lumens per Watt output characteristics.
Same lighting fixture may not have a "Universal" Lamp Socket means - like Medium Based Screwshells, they need to be designed for specific Lamps.

Other lighting may be used in conjunction with the +40 Lumens per Watt stuff, but must not be the "Primary" lighting source, and they need to be switched separate from the High Eff. "Primary" lighting source.

Check out and download the stuff found in the links given. If needed, just choose to download the Residential Compliance Manual + Compliance Forms, and if possible, choose to save the stuff which deals with Lighting only.

OK now I haven't done it.....

But couldn't 40 lumens per watt be covered by HID Metal Halides.

"The kitchen lights don't work!" - "Oh I just shut them off, you'll have to wait 15 minutes."

And they cut you slack on lighting calc's for having wider and taller windows. And they cut you slack for heating calc's for geothermal heat pumps. Now what about having solar, or wind generated electric powered Primary, or General lighting for the Kitchen and Bath? Would you then be exempt from T-24?

Big news. Title 24 has changed significantly, effective 1/1/05. This is a statewide regulation in California, and it does not have to be adopted by the locals as does the NEC. The building departments are required to enforce it.

The Title 24 requirement for the primary lighting in the kitchen and bath to be high efficiency (i.e., dedicated fluorescent) has been replaced with requirements that a certain percentage of the wattage for each of those rooms be high efficiency. I believe it's 80 percent...which means that from a practical standpoint, all the lighting for those rooms has to be fluorescent. At least that's the way I read it.
