Abstract
An extender or cover is provided for fitting over partition walls between adjacent sets of terminal points or connectors on an electrical terminal block. When installed, the extender serves as a mechanical barrier against inadvertent connection of terminals of different electrical polarity or potential. The extender also serves as a visible cautionary indicator, alerting the service crew to be aware of the risk of misconnection.
