High power electrical connections
It is critical that the high-power electrical connections are done correctly to ensure safe,
compliant, and warranted performance of the charging equipment.
SAFETY WARNING!
Only trained and competent electricians are authorised to perform this work.
•
Ensure that the upstream power feeds are off and locked out throughout the work.
•
The charging equipment must not be energised at any time during the installation. To
ensure personnel and equipment safety, power will be applied for the first time during
the commissioning phase.
•
Ensure that the cables used meet the minimum requirements specified by Tritium.
•
Ensure that the lugs are compatible with fine strand cable, and that the crimping die is
correct for both the wire type and lug type.
•
Double check lug, cable, and crimp die compatibility.

•
A small amount of
copper
jointing compound must be applied to the contact patch of all
lug to copper busbar connections. This inhibits corrosion at the joint to maintain a good
connection for the life of the charging system.
•
Use a flat washer in contact with the top of the lug and a spring washer on top of the flat
washer for all bolted lug connections.
•
Torque all connections to the specified amount and mark the torque with a paint pen
immediately.
•
Clearly label all cables. Relabel when a cable is shortened, if required.
•
Mark all cables with colour coded heat shrink.
•
Do not cover the entire lug with heat shrink; leave one crimp mark showing so that the
correct crimping tool stamp is shown.
