发明名称 Front trim for panelboard
摘要 The front trim of a panelboard consists of a front plate having an interior opening surrounded by a rearwardly extending lip, and a face plate having a forwardly extending lip disposed in telescoping relationship with respect to the lip of the front plate. Adjusting means are provided to move the face plate forward and rearward while the front plate and the panelboard interior remain stationary. The face plate is provided with twist-outs which are pressed forward so that during removal thereof they cannot be punched to the rear into engagement with live conductors of the panelboard interior.
