As promised, in this week's blog post I thought I would summarize the content of the session my property managers and I attended on the need for electrical preventive maintenance. We have already been practicing PM for our electrical systems, mainly thermography of our electrical panels. We thought we had it nailed. Get a thermographer onsite every couple of years, and make the fixes they recommend.
Well, according to the presenter of this session at the expo, that plan was not good enough. Resistance testing, visual inspection of connections are also an important part of electrical preventive maintenance. And to be the most effective, it should be done every year.
And then every 3 years, there should be "de-energized" maintenance. Yes, that means turning the power off to the whole building, and checking it all out.
I guess we will be re-considering our electrical maintenance program.
