The Club’s technical team answers your pressing questions – this month we look at electrical hook-up (EHU) cables.
A The electrical installations in your leisure vehicle and on campsites are controlled by British Standard BS 7671 (IET Wiring Regulations) and the specification of the hook-up cable is included within that.
While the Wiring Regulations are non-statutory (ie they’re not in themselves a statement of law), they’re referenced in several UK statutory instruments, so for most practical purposes, they have legal force as the appropriate method of electrical wiring.
The basic specification defined by the Regulations for any EHU cable assembly is:
New leisure vehicles which are certified via the National Caravan Council’s Manufacturers’ Approval Scheme should be supplied with a cable to the above specification. These cables don’t last forever, though, and should be replaced with another of similar specification when required. Any cable which is showing visible deterioration – eg damage to the outer sheath or signs of overheating – is likely to need replacement, so check whenever you coil or uncoil it.
A basic check of the cable’s condition is usually included in an annual service, but a more thorough test which will indicate any internal deterioration of the conductors will usually only be included in an Electrical Installation Condition Report (EICR), the more comprehensive check on the condition of a leisure vehicle’s electrics which is recommended to be done every few years.
Don’t skimp on the quality of an EHU cable – it’s a safety-critical part of the electrical supply to your vehicle. A good one should give many years of safe, reliable service.
