[QUOTE="Sidney, post: 494832, member: 30039"] Is you PSSC enough to disconnect the OCPD within the required time for a TT system? Do you have additional protection? If the answer to both of the above is yes then you should be good to go. PSSC will be enough for short circuit faults and a 30mA RCD will be suitable for earth faults. For some strange reason I like working on TT systems. [/QUOTE]
