Loose Wire

• 

A loose connection inside a stairwell lighting board or fitting can cause total circuit failures that are often mistaken for burned-out bulbs or dead ballasts. On a recent callout in an Edinburgh tenement, a single loose wire caused a complete failure of one light circuit—leaving one fluorescent tube in every fitting across the building completely off.

Loose wiring creates high electrical resistance, leading to intermittent power delivery, flickering, and heat build-up. To safely resolve the issue and protect the stairwell from further faulting, we:

• Conducted diagnostic circuit testing across the main lighting board.

• Located the disconnected conductor and safely re-secured the wiring into the terminal block.

• Fully tested both lighting circuits to ensure proper power distribution across all floors.

Prevent unexpected circuit failures and keep your communal lighting reliable. Upgrade your system controls with an astronomical Timeclocks setup, reduce ongoing maintenance with a complete LED Conversion, or review our clear Pricing for stairwell fault finding and repairs across Edinburgh.
