Protection by MCB or RCD/BO

[StaticSteve]

Am I correct with my interpretation of a/c protective device need not necessarily be RCD or RCBO depending upon install methods of cabling to inverter isolator and also dependant upon the inverter type. Protection by a type B MCB is ok. Sorry if this been mentioned before.Steve.

protect your ac cable as you would normally, your dc cable will not be protected by an mcb (in most circumstances) but protection by a tyope b RCD maybe required depending on what inverter you have and what protection settings that has.
