End feed units are used on the ends of busbar risers which are cable fed. They can be on top or the bottom of the busbar. Centre feed units are used in the middle of busbar risers which are cable fed.
The size of end feed required depends on a number of factors:
- rating of busbar
- size of cable
- number of cables
- use of a protective device or isolator
