2.2.2.7 Busbar tee-offs
With single, air-insulated busbars
Tee-off to the vertical busbars for outgoing feeders is
carried out in the case of single main busbars by means of
an angled clamp and a hexagonal socket-head bolt M12.
The length of the bolt depends upon the dimensions of the
horizontal main busbars and the thickness of the busbar
tee-off.
Dimensions clamping-bolts
Bolthlengths L1 = Height of hor. 20 ÷ 30 + H (height brances)
Bolthlengths L2 = Height of hor. 25 ÷ 30
Torques: see par. 4.1.1
In the case of a single busbar system,the busbars are fitted
in the rearmost openings of the busbar clamping device,
see Figure 2-49. The clamped strips are always fitted in the
front of the phase and neutral busbars. The length of the
clamp-strip is the same as the height of the horizontal main
busbar. Underneath the clamping bolts a serrated cupped
washerand a flat washer are fitted.
