2014 CODE CHANGE
This weeks post is for a new 2014 Code change (December 2017 Adoption date). Section 210.52 (G)
outlets in garages. We will have to install one for each space, and they won’t be able to feed lights on
the outside of the garage.
THIS IS A 2014 CODE CHANGE WHICH IS NOT IN USE AT THIS TIME. STATE OF FLORIDA IS LOOKING AT
DECEMBER OF 2017 TO ADOPT THIS CODE.
Till Next time be safe work safe and Merry Christmas!!!

New Product GFCI/AFCI outlet
During my trip out on Black Friday I found a new product that should help solve some of the problems I have run into out in the field. The product is a GFCI/AFCI receptacle outlet, both 15 and 20 ampere. Thought this may help with the problems of, “How do I get AFCI protection there”. Check out the link below to see this new outlet.

Replacement Kits for old panels
Both Eaton and Square D have retro kits for replacing old panels. Some of these kits are guts only or the whole panel fitting in an old small space.
See the attached link to Eaton retro kit, I will post the Square D one when I find it.

Code Change missed.
This weeks Code change comes from section 210.52(E)(3) outlets on Balconies, porches, or decks. In the 2008 Code it was required to be at 20 square feet before requiring an outlet on a balcony, porch or a deck. In the 2011 NEC they took out the 20 square foot requirement and now mandate an outlet on any size balcony, porch or deck.
Till next time be safe

Always heard of this but never seen one.

Sizing a service 230.90(A) Exception 3 and FBC Residential E3603.3.1 Exception.
This weeks post comes from a couple of questions asked these past couple weeks about sizing a service. I was asked why you have to add the breakers up to get the size of the main! I told them to look at section 230.90(A) Ex.. #3in the NEC and in the Florida Building Code Residential E3603.3.1 exception. This is not a new so I don’t understand how someone could come to the conclusion that the main “MUST” be based on adding up all the breakers in the panel or all the mains at a service. The exception to this section allows us to size the main based on a calculation, and not by adding the breakers together, because if that was the correct way to size the main I would need 600 amps for the main in my home and my 2/0 wire would be way to small. In the slides below there is a 400 ampere service with four 200 ampere mains, which to the layman would look like an 800 ampere service but in reality it is only a 400 ampere service, because the calculated load was only 340 amperes and we used 500 Kcmil Cu. wire which has an ampacity of 380 amperes at 75c which is good for a 400 amp service see 240.4(B).
Hope this helps.
