Emissivity of a Bees’ Nest?

Level III student Gabe Peer of Travis Electric Company in Nashville, TN recently sent his instructor, Ron Lucier, a set of images he took of a disconnect on a roof unit.  It turns out disconnects on 10 of the 11 units present on this particular roof contained some kind of nest!

Which begs the question…any guesses on what emissivity to use if your fuses are covered with a wasps’ nest? Does it even matter?  All joking aside, I know that a number of thermographers out there have had similar, less-than-pleasant, encounters with wildlife while in the field.  As if dealing with PPE isn’t enough to worry about, from insects, to rodents to reptiles there’s always the potential for a nice surprise to jump out at us from under an electrical cover.

  1. Instead of using 3M electrical tape, perhaps BandAids would be more appropriate?

    In a coal fired power plant years ago we opened a door only to have it tear apart a white faced hornet's nest on the other side. My electrician and I were stung multiple times. You never know what's on the other side of a door, it might not be a hot connection!
