Door sensing fuse block with side extending rotary disconnect

The present invention relates to electrical fuse blocks for mounting in cabinets and having rotary disconnect shafts extending out of the cabinets to a handle, and in particular, to a fuse block in which the handle may be mounted on the side of the cabinet yet which provides an interlock limiting operation of the fuse block when a cabinet door is open. A fuse block for cabinet mounting provides a shaft that may exit a side of the cabinet to be received by a handle mounted on that side. A finger attached to the inner cabinet door provides for an interlock by engaging with a bolt communicating with the shaft preventing inadvertent opening of the cabinet when the fuse block is connected to power and/or connecting the fuse block to power when the cabinet door is open.
