Faithfull Site Power for UK Tradespeople — Extension Reels, Trailing Leads and Transformers

Getting power to the right place on site is one of those unglamorous details that decides whether a job runs smoothly or grinds to a halt. A 25-metre reel that doesn't unspool cleanly, a trailing lead that trips an RCD when it gets damp, or a transformer that's not up to running a twin-socket 110V tool chain — each one costs time and credibility. Faithfull's site power range is built for UK trades: rated to the voltages and socket types you actually use, with cable lengths that cover real job-site distances.

APM Electricals stocks the full Faithfull site power line at trade prices with next-day delivery available. Whether you're setting up a domestic extension, running a commercial fit-out, or keeping a civils crew lit after dark, there's a product here for you.

Choosing the Right Site Power Setup

240V extension reels: domestic and light commercial

For most domestic renovations — kitchens, bathrooms, loft conversions — a 240V 13A extension reel is the practical choice. No transformer needed, plug directly into the consumer unit supply or a temporary supply board. The Faithfull 25m reel covers virtually any domestic room span. Key rule: always fully unspool the reel before connecting power tools. A coiled reel running current builds heat in the cable that accelerates insulation degradation. This isn't Faithfull-specific — it applies to any reel.

110V trailing leads: commercial, civils, and H&S-controlled sites

Many principal contractors and developers mandate 110V tools on site for health and safety compliance. The centre-tapped earth design limits shock exposure to 55V rather than 240V, a meaningful risk reduction where cables are exposed to damage, wet conditions, or high foot traffic. If your customer is a housebuilder, main contractor, or social housing provider, 110V is almost certainly a requirement. Stock the trailing lead alongside the transformer — clients who buy one typically need both.

3kVA vs 5kVA transformers

The Faithfull 3kVA dual-socket transformer is rated for two medium-draw tools simultaneously — think SDS drill (600–900W) plus a site light or smaller angle grinder. If your customer routinely runs two full-power angle grinders or a large site mixer on 110V, they need a 5kVA unit. For most single-trade setups (one spark, one plumber, or one joiner), 3kVA is sufficient and more portable.

Festoon lighting: site and seasonal

110V festoon is the safe choice for site lighting — runs off the same transformer as the tools, eliminates the need for a separate 240V run to the lighting circuit. The 22m span suits a standard terraced house or a medium-sized commercial unit. For outdoor events or permanent garden installations, 240V festoon is more common, but on a live construction site 110V keeps the H&S risk profile consistent.

Site Power Checklist for Tradespeople

• Check site voltage requirements before pricing up — 110V mandates affect tool hire and transformer costs.
• Always unspool extension reels before use — coiled cable overheats under load.
• Inspect leads and reels before every use — damaged sheathing on a 110V lead is a reportable near-miss on most sites.
• Match transformer kVA to anticipated load — running two 1kW tools simultaneously needs at least a 3kVA unit.
• Use yellow 110V connectors throughout — mixing 240V and 110V leads on site is a tripping hazard and a compliance failure.
