12.3.4 Loop resistance and prospective fault current
The definition of the nominal voltage for calculating I
PFC
is modified as follows:
- 55 V for selection of a single-phase center-tapped network,
- 63 V for selection of a three-phase network.
- 63 V for selection of a three-phase network.
The test can be carried out for both combinations (L1-PE and L2-PE). For each individual test re-
sult, the corresponding indication is shown.
