An important requirement of cable management under AS 3000 is the use of bootlace ferrules—or other similar means—to ensure an appropriate connection is made, copper creep minimised (which results in loose connections, an increase in contact resistance, heat, and possible arcing and fire) when terminating fine-stranded cable. In the case of standard AC cable—that is not fine stranded—this is not so clear and standard practice is to twist and double over.
iEnergytech has been conducting research to establish whether installing bootlace ferrules on standard TPS cable (for instance) will reduce copper creep or not. Different types of switch terminals are being experimented with.
In our pursuit to ensure we have the right solution for cable terminations we have engaged in dialogue with global leaders, including NASA.
