Connection diagram of a four-conductor system
Arrange the cables as shown below to get an as equal current distribution as possible.
Connect single-core cables without concentric protective shield (armor) as shown below.
WARNING! Ground all conductive cable supports, cable clamps and individual
conductive items close to cables, such as cable trays. A dangerous voltage can
become present on the non-conductive outer sheath of the cable. This can cause
injury or death.
