Work Lighting and Site Illumination

Adequate lighting proves essential for quality work, safety, and productivity. Poor lighting causes eye strain, increases accident risk, and makes precise work nearly impossible. Modern LED technology has transformed work lighting, delivering exceptional brightness with minimal power consumption and generating far less heat than traditional halogen alternatives.

Rechargeable Work Lights

Cordless LED work lights provide portable illumination without trailing cables. Modern lithium-ion batteries deliver several hours of runtime at high output, with lower settings extending operation throughout a working day. SCANGRIP specializes in professional rechargeable work lighting, offering over 230 products designed specifically for trade applications.

Rechargeable inspection lights suit tight spaces and detailed work. Magnetic bases and hanging hooks provide hands-free positioning. Flexible neck designs direct light precisely where needed. For general site lighting, rechargeable flood lights deliver broad illumination for multiple workers. Some models integrate power bank functions, charging phones and devices from their internal batteries.

Headlamps keep light directed wherever you look while leaving both hands free. Essential for electricians working in ceiling voids, plumbers under sinks, or anyone working in confined spaces. Modern LED headlamps provide exceptional brightness with extended battery life, and many offer both flood and spot beam options.

Mains-Powered Work Lights

For extended use or stationary applications, mains-powered LED work lights provide unlimited runtime without battery charging concerns. Site lights on stands illuminate large areas for multi-person work. Smaller task lights focus illumination for bench work and assembly. Halogen work lights still serve applications requiring intense heat alongside illumination, though LED alternatives now match their light output with far lower power consumption.

Emergency and festoon lighting creates safe working environments after dark. Multiple lamps on a single cable string provide distributed lighting across work areas. Heavy-duty construction ensures these lights withstand site conditions including impacts, moisture, and dust exposure.

Torches and Portable Lights

Compact torches belong in every toolkit for checking dark spaces, emergency use, and general illumination. LED technology means even small torches deliver impressive output. Tactical torches provide intense beams for long-distance illumination. Lanterns offer 360-degree light for camping, emergencies, and general area lighting.

Specialist torches include explosion-proof models for use in potentially explosive atmospheres, UV torches for leak detection and curing applications, and red-light torches for preserving night vision. Brands like Energizer and Duracell provide reliable torch solutions from basic single-LED models to high-performance multi-cell units.

Extension Leads and Power Distribution

Bringing power to where work happens requires proper extension leads and distribution equipment. Cheap, inadequate cables create fire risks and voltage drops that damage tools. Quality extension leads deliver safe, reliable power distribution for professional applications.

Extension Leads and Cables

Cable rating determines safe current capacity. Underrated cables overheat, potentially causing fires or melting insulation. For general power tool use, 13A-rated 1.5mm² cable suits tools up to 3000W. Heavier equipment or multiple simultaneous loads require 2.5mm² cable rated for higher currents.

Cable length affects voltage drop—longer cables experience greater voltage loss, potentially causing tools to underperform or overheat. For site work, multiple shorter extensions often prove better than single very long runs. Fully unwinding cable reels prevents overheating from inductance effects that occur when cables remain coiled under load.

Outdoor extension leads need weatherproof construction with sealed connections and appropriate IP ratings. Bright colours improve visibility, reducing trip hazards. Some extensions incorporate RCD protection directly within the cable or plug, providing personal protection against earth faults.

Cable Reels

Cable reels provide neat storage and safe deployment of long extension cables. Industrial reels deliver 25m, 50m, or longer cables with thermal cutouts preventing overheating. Caravan and camping reels offer portable power distribution with multiple sockets. Always fully unwind reels under load—even moderate current through coiled cable generates heat that can melt insulation.

Professional cable reels include features like IP-rated sockets for outdoor use, thermal reset switches that prevent operation until cables cool, and cable guides that facilitate neat winding. Heavy-duty frames protect reels from site knocks and provide stable positioning.

Distribution Boards and Splitters

Site distribution boards turn single power sources into multiple outlets, often incorporating RCD protection and individual circuit breakers. These units provide safe power distribution for multiple tools and equipment simultaneously. Portable designs allow repositioning as work progresses, while weatherproof construction ensures reliability in all conditions.

Simple socket splitters convert one outlet to two or more, useful for occasional multi-tool use. However, remember that total current draw must not exceed the supply rating—plugging multiple high-draw tools into a splitter can overload circuits even though everything physically connects.

RCD Protection and Electrical Safety

Residual Current Devices (RCDs) protect against electrocution by detecting earth leakage and disconnecting power within milliseconds. For construction sites and outdoor work, RCD protection proves essential—UK regulations require RCD protection for portable tools used outdoors or in damp environments.

Plug-in RCDs fit between the socket and equipment plug, providing portable protection. RCD adapters convert non-protected outlets to protected ones. Inline RCDs within extension leads offer protection for everything downstream. Test RCDs regularly using their built-in test buttons—monthly testing ensures these life-saving devices remain functional.

Different RCD sensitivity ratings suit various applications. 30mA devices provide personnel protection, tripping on very small earth leakage that might cause electrocution. Higher-rated RCDs (100mA, 300mA) protect against fire risk from larger earth faults but won't necessarily prevent fatal shocks—these suit equipment protection rather than personnel protection.

Batteries and Power Sources

Cordless tools and equipment rely on batteries for mobility and convenience. Understanding battery types and proper care extends life and maintains performance.

Disposable Batteries

Alkaline batteries remain the standard for low-drain devices like torches, remote controls, and measurement equipment. AA and AAA sizes suit most portable devices, with C and D cells powering larger torches and equipment. Lithium disposable batteries offer superior performance in extreme temperatures and longer shelf life, valuable for emergency equipment and infrequently used devices.

Buy quality branded batteries from reputable manufacturers. Cheap alternatives often deliver poor performance, leak prematurely, or provide vastly less capacity than claimed. Brands like Energizer and Duracell have earned their reputations through consistent performance and reliability.

Rechargeable Batteries

NiMH rechargeable batteries suit regular-use applications where disposable battery costs become prohibitive. While initial cost exceeds disposables, rechargeables pay for themselves through repeated use. Modern low-self-discharge NiMH batteries maintain charge for months, overcoming traditional rechargeable limitations.

Lithium-ion batteries dominate power tool applications, offering high energy density, no memory effect, and minimal self-discharge. These batteries require specific charging systems matched to their chemistry—never attempt to charge lithium-ion batteries with chargers designed for other battery types.

Electrical Installation Accessories

Beyond power distribution and lighting, numerous electrical accessories support professional installation and maintenance work.

Cable Management

Cable ties, clips, and conduits organize and protect electrical installations. Proper cable management prevents damage, simplifies troubleshooting, and creates professional-looking installations. Self-adhesive clips secure cables to surfaces without drilling. Conduit protects cables in exposed locations or where mechanical damage might occur.

Cable trunking conceals surface-mounted cables while providing easy access for modifications. Flexible conduit protects cables while accommodating movement. Heat-shrink tubing insulates connections and provides strain relief.

Connectors and Terminals

Quality connectors ensure reliable electrical joints. Crimp connectors provide permanent connections for automotive and low-voltage work. Terminal blocks facilitate multiple wire connections in control panels and junction boxes. Wago-style lever connectors allow tool-free connections with reliable contact.

For temporary connections, chocolate blocks and junction boxes provide accessible joints that can be modified as needed. Proper connections prevent voltage drops, overheating, and potential fire risks from poor contact resistance.

Testing and Measurement

Voltage testers confirm whether circuits are live before working on them—essential safety equipment for any electrical work. Non-contact voltage detectors sense live conductors without direct contact, useful for cable route tracing. Multimeters measure voltage, current, and resistance for diagnostics and verification.

Socket testers quickly check wiring correctness in power outlets. RCD testers verify that RCD protection trips correctly and within required timeframes. Continuity testers confirm complete circuits and identify breaks or high-resistance joints.

Generator Compatibility and Power Quality

When working away from mains power, generators provide electricity, but power quality varies significantly between generator types. Inverter generators produce clean, stable power suitable for sensitive electronics and charging equipment. Conventional generators may produce voltage spikes and frequency variations that damage electronics or prevent battery chargers from operating correctly.

Match generator capacity to your load requirements. Running generators near maximum capacity shortens life and increases fuel consumption. Size generators to provide 30-40% overhead beyond your maximum expected load. Consider starting currents—motors draw several times their running current when starting, requiring generator capacity to handle these surges.

Storage and Maintenance of Electrical Equipment

Electrical equipment requires proper storage to prevent damage and maintain safety. Store extension leads coiled loosely—tight coiling damages cables internally. Check cables regularly for cuts, abrasion, or damage before use. Replace damaged cables immediately—repairs prove false economy when safety is compromised.

Keep battery contacts clean to ensure good electrical connection. Store rechargeable batteries partially charged rather than fully discharged for longest life. Clean work lights and equipment to prevent dust buildup that might cause overheating or short circuits.
