Dear All,
I have been an outspoken critic of module level shutdown for all the reasons
folks do. However, I have come around. We have witnessed too many systems
where rooftop wiring has been chewed up by critters... mostly squirrels. We
have seen everything from residential fires to holes in metal roofs caused by a
DC arc. I never thought I would see the day when I would not only be thinking
MLSD is a good idea but advocating for it.
Smiles,

So far the module level shutdown requirements have been a real blow to our
industry. The reliability and cost from a maintenance and installation
standpoint has been very hit or miss so far. It feels like this requirement was
rolled out far too quickly without enough forethought to its impact on the
industry. We are constantly going out and fixing problems with mlsd installed
by other contractors. Thankfully the problems have nothing to do with the
quality of the installations. The problems are almost all due to premature
failure of the products or some inherent defect in them. This is a serious
issue costing the industry time and resources and making our installers less
safe. It just doesn’t really accomplish the intended goal of the requirement.
I’m curious how other wrenches are dealing with this issue. I recently became
aware of fixMLSD.com which appears to be focused on bringing a more sensible
approach to this requirement.
Your thoughts are appreciated,
Sky Sims
