Electric Hook-Up (EHU)
Also known as: EHU, shore power, mains hook-up, campsite electric
A campsite mains connection: a 230V supply you plug into via a dedicated lead, letting the van run mains appliances and recharge its leisure battery.

Electric hook-up (EHU) is the British campsite term for shore power. You connect with a CEE 'commando' lead — the blue round 16A connector — from a site bollard to the van's inlet, feeding a consumer unit with an RCD for safety.
Pitch bollards are typically rated 6, 10 or 16A depending on the site, but many older or busy sites limit the bollard to 6A or 10A, so a fan heater plus a kettle can trip it. In winter, hook-up is how a non-solar or lithium van keeps the leisure battery full and runs a mains charger; for an all-electric build it is the honest fallback when short British days starve the solar. Always check the site's amperage before relying on it.
