55v - 110v centre tap transformer short circuit calculations

Anthony Sullivan

hello

i have been trying to work out how to work short circuit calculations for 110v systems. do i use 55V with c max or do use 110v or even use a 3phase calculation. i am trying to work out if a circuit will trip on 16A c type mcb for short circuit as i am putting a rcbo in to cover the fault current. 

110v 55v 

0.85ohms line to line tested

4mm 2 core cable

    Why 4.0 mm two core cable?

    What is the output rating of the transformer?

    Does the transformer already have fuses in it on the output?

    Is it a fixed installation or temporary?
