NFPA 72 17.7,3,2,1 Proper Mounting of Smoke Alarms

Categories: News & Stuff - Tags:

Contractors and inspectors still call and ask about the location of smoke alarms, they want to make sure that the location they put it in is OK.

As shown above it is OK to mount a smoke alarm right up against the ceiling on the wall, there’s no longer that space of 4” down from the ceiling or 4”

away from the corner on the ceiling.  The space 12” down from the ceiling is to the top of the detector.  This changed in the 2010 NFPA 72.  Hope this helps.

Some changes aren’t always better.

Categories: News & Stuff

This Table from the Florida Building Code has been removed, and replaced by the new calculation using 83% for residential services.  Just as they did in the NEC the FBC removed an easier way to size residential conductors and overcurrent devices by replacing it with a calculation.  All changes aren’t necessarily better.  The table shown not only gives us the conductors and overcurrent device sizes it gives us the grounding electrode conductor size also.  Make a copy and stick it in your code book for easier reference or Email me and I’ll send you a PDF.

Till next time be safe work safe, and Happy Birthday to our son Aaron who turns 26 today.

Happy Birthday we love you.

Florida Building Code Residential Electrical Code

Categories: News & Stuff

This weeks post comes from the Florida Building Code Residential Electrical code from Chapters 34 through 45.  Inside each chapter they have given us some of the best illustrations that I’ve seen. So every now and then I will pull up one or two to show you.  This one shows the clearances from overhead services to platforms , widows and  the like.  A good illustration on what the code implies (230.9).

Categories: News & Stuff

This weeks change allows us to use the steel frame of a building in place of running a conductor all around a building.   Bonding each item that needs to be bonded into part of the Grounding Electrode system.  Such as the case of the electrical service on one side of the building and the cold water service on the other.
