Jeff Cote of Pacific Yacht Systems explains the correct sequence for stacking electrical terminals on bus bars, circuit breakers, and fuse holders to prevent voltage drop.Watch Stainless steel hardware is effectively non-conductive, so the ring terminal must make direct contact with the terminal block or breaker surface.1:13 Placing a stainless steel washer between the ring terminal and the contact point creates unnecessary resistance, which causes significant voltage drop under high current loads.2:19 The proper assembly order requires placing the ring terminal directly against the conductive surface, followed by the flat washer, the lock washer, and finally the nut or bolt fastener.1:57 This stacking method applies to all electrical connections, including battery terminals.2:32 Improperly ordered connections often pass static voltage tests but fail under load.2:19 Regularly inspecting these connections during electrical audits ensures system integrity and prevents hidden resistance in the circuit.2:54
