2007 Series Topjob S current transformer disconnect terminal blocks with Cage Clamp S spring-pressure technology for conductor sizes 20–8 AWG have an intuitive orange three-position (operating, shorting and measuring) disconnect lever. Touch-proof design does not require a separate cover. Four marking locations help ensure wiring accuracy: on the disconnect link, on top of the terminal block and on the sides. Marking is provided via WMB marker tags or a continuous marking strip.
