I understand that daisy chaining together 2 or more power strips/surge protectors is a no-no per a UL Standard and doing so violates 110.3(B) of the NEC. What I am having problems with is understanding the theory behind why that is not allowed. I have heard that you could have circulating ground loops/current between the two strips which would put objectionable current on the EGC. I also have read that you could get voltage drop from putting too many of these things together. Anyone have an opinion?
