The Complete Guide to Camping and Outdoor Electrical Accessories — Hookup Leads, Adaptors, and Powering Your Pitch

How Campsite Electrical Hookup Works

Most established campsites provide electric hookup (EHU) — a power supply post on or near each pitch, fitted with a standardised socket. You connect your own cable between the site post and your tent, caravan, or motorhome.

The supply is typically limited — commonly to 10 or 16 amps (the exact figure varies by campsite and country). This is significantly less than a domestic household supply. Running high-powered domestic appliances (fan heaters, hair dryers, kettles rated above 1,000 watts) can overload the supply, trip the circuit breaker, and cut power to your pitch and potentially your neighbours.

Understanding the supply limit, using appropriate equipment, and managing your electrical load are the fundamentals of safe and reliable campsite power.

Hookup Leads — Choosing the Right Cable

The hookup lead connects the campsite power post to your tent mains unit or caravan inlet. It is the single most important electrical accessory — and the one where quality and specification matter most.

Cable specification. A hookup lead must use outdoor-rated, flexible cable with a minimum conductor size of 2.5 mm². The outer sheath should be highly visible orange (the standard for camping cables) — making it visible on grass and gravel to prevent trip hazards. Arctic-grade or tough-rubber cable survives outdoor conditions; standard domestic cable does not.

Connectors. The plug end (connecting to the site post) is a blue industrial connector (CEE-form, typically 16A). The socket end depends on your setup — a blue industrial socket for caravans and motorhomes, or a weatherproof mains distribution unit for tents.

Length. Hookup leads are typically available in 10, 15, 20, and 25-metre lengths. The campsite power post may not be immediately adjacent to your pitch — carry a longer lead than you think you need. A 25-metre lead covers most situations.

Always fully unwind the cable. A coiled or partially wound cable generates heat within the coil under load. Over time, this can melt the insulation and create a fire or shock hazard. Unwind the entire length of cable, even if you only need a portion of it.

Do not use domestic extension leads outdoors. Household extension leads are not rated for outdoor use — they lack weatherproofing, use thinner cable, and do not meet the safety standards required for campsite power connections.

Mains Distribution Units for Tents

A mains distribution unit (sometimes called a mobile mains unit or tent hookup unit) is a weatherproof box with multiple sockets, connected to the hookup lead. It provides safe, protected mains power inside a tent or awning.

Key features. A built-in RCD (residual current device) that trips if a fault is detected. A built-in MCB (miniature circuit breaker) that trips if the current exceeds the safe limit. Multiple weatherproof sockets (typically three to five) for connecting appliances. USB charging ports (on newer models). A hanging bracket or hook for mounting off the ground (keeping the unit above damp surfaces).

The mains unit must be IP44 rated or higher — meaning it is protected against splashing water and solid objects larger than 1 mm. This is the minimum weatherproofing standard for outdoor electrical equipment.

Position the unit inside the tent or awning — raised off the ground on a hook, table, or shelf. Never place it directly on wet ground.

Caravan and Motorhome Mains Connection

Caravans and motorhomes have a dedicated mains inlet — a weatherproof socket on the exterior of the vehicle that accepts the hookup lead's blue industrial plug. Inside the vehicle, a consumer unit (similar to a domestic fuse board) distributes power to the internal sockets and appliances.

The consumer unit includes an RCD and MCBs — providing the same fault protection as a domestic fuse board.

Reverse polarity is a common issue on some campsites (particularly in mainland Europe) where the live and neutral connections are reversed at the site post. Most modern caravans and motorhomes include a reverse polarity indicator. If reverse polarity is detected, a polarity reversal adaptor corrects the issue. Do not ignore a polarity warning — it compromises the safety of your electrical system.

RCDs and Circuit Breakers — Non-Negotiable Safety

An RCD (residual current device) monitors the balance of current flowing through the live and neutral conductors. If a fault causes current to flow to earth (through a person, through a damp appliance, or through damaged cable), the RCD detects the imbalance and cuts the power in milliseconds — fast enough to prevent a fatal electric shock.

An MCB (miniature circuit breaker) trips if the current exceeds the rated capacity of the circuit — protecting the cable and appliances from overload.

Your own RCD is essential even if the campsite post has one. The campsite RCD protects the site infrastructure — your own RCD protects you. Double protection (site RCD plus your own) provides redundancy. If the site RCD is shared between multiple pitches, a fault on a neighbouring pitch could trip the site breaker and cut your power.

Adaptors and Converters

Blue-to-domestic adaptors convert a blue industrial socket to a standard domestic three-pin socket. These are useful for connecting standard domestic appliances to the campsite supply, but they must be rated for outdoor use and should only be used in conjunction with an RCD-protected circuit.

Plug-top adaptors for European touring convert between different national socket types. Campsite hookup connectors vary across Europe — the blue CEE-form connector is standard in most countries, but some older sites and some countries use different formats.

Splitter leads provide two blue sockets from a single blue plug — useful if you need to run a separate lead to an awning or second tent. However, both circuits share the same site supply — the total load must not exceed the pitch's amp rating.

Cable Management

Cable reels and tidies keep hookup leads organised in storage and prevent tangling. A dedicated cable reel allows you to unwind the exact length needed (remembering to fully unwind under load).

Cable protectors (rubber ramps that sit over the cable on the ground) prevent the cable from being driven over, tripped on, or damaged at path crossings.

Cable stakes or clips hold the cable close to the ground and along the edge of the pitch — reducing trip hazards and keeping the cable out of the way.

Low-Wattage Appliances

Campsite hookup supplies are limited — typically to 10A (2,300 watts) or 16A (3,680 watts). A standard domestic kettle draws 2,000–3,000 watts alone — potentially exceeding the entire pitch supply.

Low-wattage camping appliances are designed to operate within campsite power limits. Low-wattage kettles (typically 750–1,000 watts), low-wattage toasters, and low-wattage heaters draw less current and avoid tripping the supply.

Manage your load. Do not run multiple high-draw appliances simultaneously. A low-wattage kettle plus a phone charger plus a light is fine. A kettle plus a fan heater plus a fridge will likely trip the breaker.

Polarity and Testing

A polarity tester (a small plug-in device with indicator lights) checks that the hookup supply is correctly wired — live, neutral, and earth in the correct positions. Reverse polarity and missing earth connections are genuine hazards that a tester reveals instantly.

Test the supply at every new pitch before connecting appliances. It takes seconds and provides assurance that the supply is safe.

Portable Power Stations

Portable power stations (battery-powered units with mains sockets, USB ports, and 12V outputs) provide mains-equivalent power without hookup. They are charged from mains, solar panels, or a vehicle's 12V socket and provide a portable, silent power source.

Uses. Charging phones, laptops, and cameras. Running small appliances (lights, fans, CPAP machines). Providing mains power where hookup is unavailable (wild camping, off-grid pitches, festivals).

Capacity is measured in watt-hours (Wh). A 500 Wh unit runs a laptop for approximately 8–10 charges, a phone for 30–40 charges, or a 60W appliance for approximately 8 hours. Larger units (1,000–2,000 Wh) run more demanding appliances for longer.

Solar panels paired with a portable power station provide renewable charging — extending off-grid capability indefinitely in favourable conditions.

USB and 12V Charging

USB charging is the most common electrical need at any campsite. Multi-port USB chargers, solar-powered USB chargers, and USB power banks keep phones, tablets, headlamps, and cameras charged without consuming significant power.

12V accessories (plugging into a vehicle's cigarette lighter socket or a leisure battery's 12V output) include phone chargers, cool box power leads, LED lights, and small fans.

A 12V multi-socket adaptor provides multiple 12V and USB outlets from a single socket — useful in a vehicle or caravan where 12V sockets are limited.

European Hookup — Touring Abroad

Campsite electrical standards vary across Europe. The blue CEE-form connector is widely used, but connector types, supply ratings, and polarity practices differ.

Carry a European adaptor set that covers the common connector variations. A reverse polarity adaptor is essential for countries where polarity reversal is common (notably France, Italy, and some Eastern European countries).

Supply ratings vary. Some European sites provide only 6A — significantly less than the 16A common in the UK. Adjust your appliance usage accordingly.

Electrical Safety Essentials

Never use domestic extension leads outdoors. They lack weatherproofing and adequate cable specification.

Always use an RCD. Whether built into your mains unit or as a standalone plug-in device.

Fully unwind all cable. Coiled cable overheats under load.

Keep electrical equipment off wet ground. Raise mains units, sockets, and connections above ground level.

Do not modify electrical equipment unless you are a qualified electrician.

Turn off and disconnect before leaving the pitch. Do not leave the hookup connected and unattended during extended absence.

The Honest Limitations

Campsite power is limited. You cannot run domestic appliances at full power. Low-wattage alternatives are essential.

Weather compromises safety. Outdoor electrical connections are exposed to rain, dew, and condensation. Weatherproof equipment and elevated positioning mitigate but do not eliminate this.

Not all pitches have hookup. Off-grid pitches, wild camping, and some basic campsites provide no electrical supply. A portable power station or solar panel is the alternative.

Cable length is a real constraint. A short hookup lead on a large pitch with a distant power post cannot reach. Carry the longest lead practical.

Choosing Electrical Accessories by Setup

Common Mistakes People Make

Using a domestic extension lead outdoors. Dangerous. Not weatherproof. Not rated for outdoor use.

Not fully unwinding the hookup cable. Coiled cable overheats. Unwind every metre.

Running high-wattage appliances on a limited supply. A domestic kettle alone can trip a 10A campsite supply.

Ignoring reverse polarity. Particularly when touring Europe. Test at every pitch.

Placing the mains unit on wet ground. Raise it above the ground on a hook or shelf.

Not carrying a long enough hookup lead. A 10-metre lead is often insufficient. Carry 25 metres.
