Notes
When bolting aluminum lugs and connectors to buss bars with steel or brass hardware, the recommended 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 metals expand and contract with temperature changes.
