Voltage Converter Wiring Incident
Recently, an attachment cord that was wired incorrectly led to a potential safety incident. A VC-4000 voltage converter was being used during troubleshooting operations, when it was discovered that the hot and neutral cord connections at the back of the unit were reversed (see picture). This effectively bypassed the on-off switch, allowing voltage to be present at the front connections (output) of the unit even when the unit was switched off. Technicians realized the severity of the issue when a spark was seen, and the technicians immediately secured the system. No one was injured.
If you use a voltage converter in your work area, now is a good time to check that the connections were made correctly. Additionally, remember that all electrical work should be done at the lowest possible energy state. If you have questions or if any additional situations are found, contact Todd Kujawa at x7006. Please also take this opportunity to review work control documents for applicable situations, analyze the hazards and then develop and implement the appropriate hazard controls.
