1. There is almost no voltage drop in this bus bar . 2. The autotransformer is connected to the bus bars by an additional circuit breaker. 3. Bus bars must make ohmic contact.4. EGA also produces anode bars and bus bars , used in the electrolytic aluminium production process. 5. The incoming bare stranded ground wire can be seen near the bottom of the neutral bus bar . 6. This bus bar is similar to the electrified or " third " rail of a subway train. 7. The current to be measured is passed through the two cores, possibly by a solid bus bar . 8. The 21st orbit saw a short-circuit occur in the bus bar serving the 250 volt main inverter. 9. Fuseholders may be secured by screws to a panel, attached to bus bars , or mounted on DIN rails. 10. The power supply bus bars on the machine spanned distances greater than three feet, and were octopus-like in design.
