[1]
Use an RH end feed unit (without monobloc).
In order to position the tap-off boxes correctly, the neutral conductor of the
riser main must be on the left side of the element.

Use one or more suspension brackets for the vertical elements, according to
the weight of the whole riser mains.
For risers that are shorter than 4 metres, fix to the base with type B brackets (see
p.42)
when longer, use a type A suspension bracket (see p. 42) every 300 kg of
risers (including the boxes).

Use a standard suspension bracket to hang the busbar every 2 metres of riser
mains.
[4] Use elements with tap-off outlets (see page 13).

[5] Use S120 fire barrier kit for each compartment floor (see page 15).

The tap-off boxes can be installed in the tap-off outlets and near the connection
between the elements.
In both cases, the boxes extend downward.
