A loose consumer unit cover poses significant safety risks, as it can expose live electrical parts, increasing the chance of electric shock or fire. Common causes include using a non-original cover, broken lugs, missing screws, an excess of cables, or damage to the cover or unit itself. While temporarily securing a loose cover with electrical tape might seem like a quick fix, it's not recommended for long-term safety. Electrical tape can lose its adhesive properties over time, potentially leading to accidental contact with live components. It's essential to address the root cause of the loose cover promptly by consulting a qualified electrician to repair or replace the faulty components, ensuring the consumer unit remains safe and secure.
