I'm an apprentice out of local 46 in seattle. I take pictures of electrical work here and there. I have a question regarding the two starter switches. Each are individually piped on the load and line side to two exaust fans in a parking garage. However, there is a nipple between the two fusable overload protection devices. Any ideas about what this nipple is for. Why are the two starter switches connected together. Any suggestions would be a great help. _thanks--Andrew.
