Possibility Of Assembling - Phoenix Mecano Rose EX e Instructions D'emploi

7. Possibility of assembling

Inside the junction box there will occur internal heat based on the transition
resistances at the clamping points as well as the cables. The maximum tem-
perature must always be lower than the maximum allowed value. Therefore
the current load of the junction box may not become too large. The maxi-
mum numbers of usable conductors as a function of the current load and on
the conductor cross section, can be inferred from the assembly table.
Measurement of current data (Imax. xxxA) on the device plate overrides the
layout diagram.
Example: Layout diagram
Diameter of connection (mm²)
max. number of terminals**
max. number of rails
max. fitting length (mm)
Possible number
of internal cables
in dependence
of the current/A
Explanation concerning the table:
1. A conductor is defined as each inserted and each connected cable.
Protective groundings and jumpers will not be regarded according this
temperature calculation.
