Also in this case the RCCB can be named GENERAL because it cuts all active lines in one movement. The green
and orange lines are isolated from mains, therefore they are not active lines.
BUS LINE
The BUS line of the floor accompanies each circuit and should be a white V line with 1 mm
2
section.
For interconnection between switchboards a FXG 2x1.0 cable should be used.
BUS line
The BUS line of the floor is an active line as it is referred to Neutral. The current is considerably small,
being maximum 0.02 A.
The BUS line between switchboards is isolated from the mains and has a voltage around 20VDC.
In case the number of ONLY commands in one segment of the BUS is higher than 50, it is necessary to introduce
a coupler. This receives the BUS at the first segment and creates a new one for the second segment.
