Safety system

A fuse insertion prevention system for preventing insertion of a fuse into a fuse holder, the fuse insertion prevention system comprising:

• one or more retaining elements configured to engage with a fuse holder;
• a cover element configured to receive and immobilize the one or more retaining elements and prevents the one or more retaining elements from disengaging from the fuse holder, wherein the cover element prevents insertion of a fuse into the fuse holder;
• and
• a core body including a slot running through the core body from an underside to an upperside thereof, the slot including dimensions configured such that:
• a tab of the one or more retaining elements can pass through the slot in a particular orientation;
• a stem region of the one or more retaining elements can rotate on its longitudinal axis within the slot;
• and
• a foot of the one or more retaining elements cannot enter the slot,
• wherein the rotation of the stem region enables the one or more retaining elements to be orientated such that:
• the foot engages with the fuse holder, and
• the tab prevents release of the one or more retaining elements from the slot in the core body.

A fuse insertion prevention device for preventing insertion of a fuse into a fuse holder, comprising:

• a plurality of retaining elements configured to engage with the fuse holder, and
• a resilient member comprising a spring, the resilient member situated between the plurality retaining elements,
• wherein:
• the plurality of retaining elements are moveable relative to each other between an engaged and a released position, such that:
• in the engaged position, the resilient member exerts pressure on the plurality of retaining elements thereby urging them apart, and
• in the released position, the plurality of retaining elements are moved towards each other and the resilient member is compressed.
