Happy Fathers Day to all you Dads. Hope this day finds you healthy and happy.
Today’s Code sections are just clarifications of a practice we have been doing for years. The Code panel made it clear the the assembly used in this application is to be listed as an assembly. See the photo below. This outlet assembly came with the box which can not be seen in the picture, the outlet and the pop up cover.
Till next week work safe be safe.
This week note is based on my experience as an inspector and plans examiner. The Florida Statute that regulates a Carbon Monoxide alarm is often misinterpreted. I have plans that show them installed in the garage and just outside the garage door that leads into the house, although these places are probably practical , they are not installed within the intent of the Florida Statute. Statute 553.885 requires that the detector be installed within 10 feet of each room used for sleeping. Installing one in the garage may cause the alarm to be a nuisance and go off all the time which could lead you to disconnect the alarm, which would defeat its purpose. Attached is a copy of the Statute please look it over and if you have any questions please email me.
Until next week work safe use a tester if needed.

It will now be a requirement of the code to install a ballast disconnect when a ballast in a light fixture is replaced. I’m not sure how we will police this section since most are replaced by maintenance people and not electricians.
Till next week work safe
These new sections require that when replaced in an area that requires these two types of outlets, they are to be replaced by Tamper , Weather or both types of receptacles.
Till next week, work safe and be safe

This change just expands the list of parts and clarifies what needs to be bonded.
Till next time work safe and be safe.

This requirement is to keep out moister, and water from entering a switch gear or panel board. I have seen where services that where ran up the side of a pole from the utility have not been sealed and when it rained water came out of the meter can. If I see it from the utility I try to get them to put duct seal or some other kind of sealant in the pipe. The pipes don’t have to be run into a piece of switchgear or other equipment to be sealed off.
Till next time work safe and be safe.

This section changed and now matches the requirements for fire-rated assemblies. You need to “IDENTIFY” your supports (ceiling wires) that you install for support of your wiring methods.
These are the ones that you install to support your EMT, MC or other types of wiring assemblies. The wires that are installed to support the fixtures are not based on the ELECTRICAL CODE and do not need to be identified. The ones installed for the support of the fixture come from the manufactures’ installation requirements and should be installed by the ceiling installer to make sure they are installed properly. The only requirement in the NEC for a fixture that is installed in a grid type ceiling system is that the fixture be screwed, clipped, or riveted to the grid, see 410.36(B).
Till Next week Work Safe and be Safe!
This section explains that the enclosures or raceways installed in the ground or underground are always considered to be a wet location and if splices are made they shall be listed and identified for the location. The conductors shall also be listed for a wet location.

This new section should have been in the Code along time ago. Just remember to add it into your
bid the next time you do a service change. This starts July 1, 2015.
Till the next time work smart and be safe.
In sections 110.24 (A)(B) the Code has made it your job to verify the available fault current at the service. You will need to field mark the equipment with the fault current that is available at your service and with the date the calculation was performed. These markings need to be legible and able to withstand the environmental conditions of our South Florida climate; sunlight and water resistant.
The available fault current will be calculated on the basis of a number of contributing factors like the size of the utility transformer and the location of the transformer in proximity to your service. The type, length, and size of conductors used in your service will also figure into the available fault current. Not marking your service will delay receiving a final inspection from your local inspector or issuance of your permit from your plans examiner. The 2011 Code goes into effect on July 1st . All plans and permits received after this date will be governed by these new changes. I am bringing these changes to your attention so it wont be a surprise when the AHJ asks.
When you sit down to figure the price for that next service change or modification, remember that in order to perform these calculations you will need information that is not readily available to you. You will need to contact the utility for some of this information. This will cost you time; and we all know time costs you money.
