Do busbars have IP ratings?
Most busbars systems have IP ratings up to IP55 which allows their use in difficult environments. However, for extreme conditions such as petro-chemical applications or outdoor applications resin encapsulated busbar is available which gives a rating up to IP68. Resin encapsulated busbar, as the name suggests, is a system where the copper or aluminium conductors are totally encapsulated in an insulating casing of flame retardant, self extinguishing epoxy resin mix, which at IP68 classes it as submersible in water (to defined limits).
