How to cover the wires if the distribution box is too low
This permanent solution involves installing a junction box to house the wire ends. The box must be appropriately sized to ensure adequate “box fill,” which is the total volume required for all wires and connectors inside, preventing overcrowding and heat buildup. Select a well-ventilated and dry place to avoid poor heat dissipation causing equipment. Exposed electrical wire is any conductor not contained within approved conduit, an electrical box, or the protective space behind a finished wall. When protective insulation is compromised or missing, the bare conductor allows current to escape, creating an immediate risk of electric shock and. The distribution box is the central hub of the home circuit and the general control of our daily power consumption. It is an indispensable electrical equipment. If there are some potential safety hazards, we can deal with them in time.
