This is from the ROC for the 2005 cycle, on a comment to expand AFCI's to all living areas:
Panel Meeting Action: Reject Panel Statement: The panel appreciates the level of protection provided by branch/feeder AFCIʼs. However, the panel wants to see the combination protection implemented before expansion beyond bedrooms. The submitter has provided comprehensive fire data; however, Panel 2, seeks to gain further information on the experience with the devices already in the field. Number Eligible to Vote: 13 Ballot Results: Affirmative: 9 Negative: 4 Explanation of Negative: KING: This Comment should
Notice, however, that the vote wasn't a landslide by any means.
Correction Tiger- AFCI's are currently required in Michigan and are included for proposed adoption for the '05 code.
George, it is my understanding that MI is not going to adopt the 2005 NEC. I thought the plan was to rewrite it to suit what they consider their requirements should be.
Actually I don't know why they are changing their method in terms of Electrical Code.
If I understand things correctly, they will be trying to make some things a bit clearer, and modifying a few things like ground wire in flex conduits, but will be doing the same as always. Except they'll be calling in the "MEC"? Michigan Electrical Code.
The MEC (Michigan Electrical Code) will be updated within the next 11 months (as proposed). the MEC consist of a rule book called the Part 8 Rules. Part 8 Rules contain permit requirements and code requirements. Also in Part 8 Rules is the reference that directs us to the NEC for all wiring that is not covered by the MRC ( the MRC is the IRC with the Michigan spin on it).
The Part 8 Rules have amendments that are to be used instead of the rules in the NEC. As proposed, the State of Michigan will be asking for 1. An EGC in all flexible raceways. 2. No limitation on NM cable with regards to construction types or building heights. 3. Not allowing Service Entrance conductors to be run to a second building on the residential property. 4. Deleted Article 547 from the NEC since the Agricultural Buildings are exempt from inspections in Michigan (don't ask)
These proposed rules have not gone to public hearing yet but soon.
