What happen to a 3 phase meter with three current and voltage coil with neutral, if its incoming two phases are interchanged at the meter terminal? Desperate to know the answer. Anybody help, please...

Remember it is a watt hour meter, it is only measuring watts used. It should not turn backwards, quit working, or anything desparate like that. Rearranging CT's alone affect nothing, rearranging phases only affects rotation of the 3 phase motors in the system, and not the meter. Also, 3 phase hermetic compressors will not be affected at all. they either go down and up, or up and down.
