Notes
When bolting aluminum lugs and connectors to
buss bars with steel or brass hardware, the rec-
ommended practice to ensure a tight connection
is to use a Belleville spring washer on top of a flat
washer under the bolt head or nut. For heavy-duty
service where the heat rise is expected to exceed
30 degrees Celcius above ambient, this procedure
maintains constant pressure as the connector met-
als expand and contract with temperature changes.
Certifications
