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.

Ever wonder when you put that service mast above the roof how far from the edge can it be or how high off the roof does it has to be.  This weeks post comes from the Florida Building Code Residential it is a graphic that will help you understand this section.  This section E3604.2.1 is a good example of how this section is interpreted, I added the red boxes for further clarification.

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).

This one comes to us from Howard B.  He tells me that we have to keep an eye on the new helpers.

If you see it send it.

Till next time be safe work safe and keep an eye out for those great pictures.

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.

This one comes from Nate in WPB.

Yes a fan was hanging from this.

Have a safe Memorial Day.

Nice box!!!!!!!!  Not only was there no box but they use NM cable this was in a Hotel Lobby.

Till next time be safe…….

In the 2014 NEC they are going to allow us to extend the connection from Grounding Electrode (concrete encased electrode)

into a wall or above grade. In the past we could only have the conductor from the rebar extending out from the concrete

encasement, now we can have the rebar extend out from the encasement for a connection.  So this will work when the

town or city will not let you make this connection in the meter can, and you have a main breakers panel as your first means

of disconnect, you bond the neutral to this electrode in the wall near the panel if needed.  As you can see in the picture on the

right the connection has to be accessible.

Till next time be safe work safe.

Picture of the week

This picture give a whole new meaning to a cut in box or should I say a cut in extension.

This was sent to me by Mike Y of Lake Worth.

Thanks Mike
