The Must Know Guide to Electric Hook Up – EHU

29 December 2020
What is Electric Hookup and what is the best?

Spending two weeks away from a power supply can simply be impractical when camping. Grabbing an electric hook up cable (EHU) and going to a campsite with electric hook up pitches is a really great way of adding a couple of luxuries to make camping life a little easier and more comfortable. It can be a little confusing knowing which cables are safe and affordable (there’s a few dodgy ones out there!) and knowing quickly about what appliances you can use without tripping out the whole campsite. Here’s a quick breakdown of all things Electric Hook Up.

How does Electric Hook Up Work?

There are lots of campsites and caravan sites that have pitches with safety tested electric power points. You simply need to purchase a safe, robust electric hook up cable (our picks are below) plug it into the point and run the cable into your tent. From there you’ll be able to plug in standard 3-pin plugs into it and use your appliances (or at least some of them). Electric hook ups are only able to power low-power consuming appliances.

You can understand a bit more about electricity here.

What appliances I can use on Electric Hook Up?

First things first, you won’t be able to just plug everything you own in and leave it all running. There simply isn’t enough current (amps) to do that and using more than the electrical point provides will see the supply trip out and stop.

Most campsites provide electricity from a 230v supply and rated at either 10 or 16 amps. Your appliances such as hair dryers, straighteners, heaters, fridges etc will all have a power requirement measured in Watts.

I wrote about what the best electric heaters are for camping. There are a few options and models so it’s worth having a read for my four favourites.

How do you know how many Watts can be used on your power supply?

It’s really simple. The maximum Watts from your power supply is simply the voltage, 230v, multiplied by the Amps, 10 for example. 230v x 10amps = 2300watts. A 10amp campsite electric hook up point will deliver 2300 watts and no more.

230v x 10A = 2300w

230v x 16A = 3680w

230v x 5A = 1150w (common on European pitches)

The electrical points are safety tested and fitted with an MCB, a miniature circuit breaker that will turn the supply off if it is overloaded. Most electric hook up points are shared between two pitches too, so if you go over your allowance then it will kill your neighbours supply as well. Not cool, especially when people use things like fridges and sterilisers. You can ask the campsite in advance as to what their supply provides.
Lets assume you’re on a 10A supply, that means you have 2300w to use.

I’ve got an electric heater here at home. Flip it over and check out the bottom to see it’s power usage. Mine is 2000w. The heater would work but you’re probably going to have to turn it off if you want to run anything else. This is why it’s a better idea to use low-watt appliances. Many appliances that are made for camping specifically, have a lesser power draw.

I’ve made a list of some of my favourites below.

What makes the Best Electric Hook Up Cable?

There are a few dodgy cables around that don’t have the right safety precautions.

It needs the following:

  • IP44 Waterproofing (minimum)
  • Built in RCD (Residual Current Device)
  • Clip for keeping it off the floor
  • 15m + Thick Cable

Household extension cables are not suitable for camping. They lack the RCD and waterproofing making them extremely hazardous to use outdoors. You could receive a fatal electric shock off one.

My personal recommendation is for the Crusader EHU but I’ve selected 2 others you may want to consider in my article for the 3 best electric hook up cables for camping and caravanning.

How to safely use an EHU whilst camping?

Besides getting a robust, safe EHU cable as detailed above there are a few other pointers for being safe with your electric hook up.

Keep your EHU unit off the ground. This will keep it away from water should you get waterlogged (it can happen without warning sometimes!) and avoid it becoming a trip hazard too.
Make sure the cable isn’t coiled or folded together. It will generate heat if it’s coiled around itself and can cause a fire hazard.
Don’t keep appliances on overnight if it doesn’t need to be. You should never really leave any appliance on unattended. If you need to make sure the appliance is secure, away from the tent wall and uncovered.

Using alternatives to free up your Electric Hook Up

You are limited in what you can run on EHU simultaneously so it’s worth trying to use alternatives. The main item that’s easily replaced is your cooking stove. We cook on a single ring burner for most weekend camps. If we’re staying a bit longer then I’ll pack a double ring and grill gas stove. It’s super fast and boils a kettle quickly. Just this will cut out the need for separate electric kettle, stove and toaster.

I wrote an article last week about the best rechargeable camping lights too, we use the Luminoodles in the tent to light it up. The only thing we tend to run is the camping heater (I did a totally cut down list of the all those out there and picked my 4 favs here), USB chargers for power packs and a camping coolbox.

Frequently Asked Questions

I’ve tried to answer as many frequently asked questions about Electric Hook Up below. If you have any more don’t hesitate to contact me in the comments below or

What is EHU for tents?

EHU is an abbreviation of Electric Hook Up. It’s the ability to have a working power outlet in your tent whilst your pitched on a campsite that provides electric power points. Grab a cable, plug it in the power post and run it into your tent. Voila! Read our guide above for all the safety details and downlow on how to use it effectively.

Do you need electric hook up for Motorhomes?

Using EHU for caravans and motorhomes is much the same as in tents. You will need a slightly different cable though. The Semloh EHU connects the external power directly to your caravan supply. Hook the cable up to your motorhome or caravan first and then run it out to the electric point. Most points are just a case of pushing the cable into the point but sometimes you have to twist it to lock it in place.

What is the best electric hook up (EHU) cable?

I’ve picked out the three best electric hook up cables for camping in this article here. Checkout the table of my favourite three.

Are there any Electric Hook Up cables with USB?

Yes! There are electric hook up cables with USB ports like this Maypole one on Amazon. These cables with extra USB ports are useful as they free up the 3 pin plugs for your main appliances. There is always the option of adding a multi-USB plug for adding USB ports to a Electric Hook Up cable.

    I reckon your emphatic recommendation of camping hook-up cables versus domestic cables is misleading, and should be reconsidered.

    1. The devices you recommend may have IP44 certification, but in my view they are not really safe. They are protected against splashes when nothing is plugged in, but as soon as you lift the lid on a socket and insert a plug you basically have a perfectly ordinary plug and socket situation, with no protection against water at all.

    2. Non-camping extension leads can have RCDs built in, too.

    I am currently getting equipped for a return to camping after a long layoff, and I shall be using a ‘domestic’ cable with sockets meeting the higher IP66 standard even when stuff is plugged in, plus RCD protection. These sockets are the kind with a hinged cover over the plug(s), and a tight seal around the live parts when snapped shut. The RCD sits within the cover, too.

    I shall need to replace the cable’s standard 13A domestic plug with a camping-style round 16A plug. Anyone who can replace a 13A plug can undertake this chore. I’ll end up with the same sort of protection I enjoy when using power tools in the garden. There is no reason to accept less complete protection when camping.

      Hey Chris!
      Thanks for getting in touch. I completely stand by the IP44 cert products (and not misleading at all) – they’re MUCH more safer than a standard domestic multiplug. Their design alone assures that splashes from within the tent are much more unlikely to slip inside the sockets and the RCD is in all the recommended items in the piece. Sure IP66 is even safer but I think hugely overkill for being inside a tent. Also, peoples knowledge of replacing plugs / cables isn’t as extensive as your own so buying off the shelf products that work and offer peace of mind is my primary concern.
      Maybe I should add that electricity, outdoors, is always a risk no matter what you use but the article picks which products I’ve used and what I’d recommend (along with many others).
      Happy return to camping! Where are you off first!?
      Thanks again Chris,

    Thinking to buy one of those IP55 dri boxes so can keep the sockets water resistant even when in use.

      That’s a really good idea. I actually didn’t know about them. Could be useful for loads of things! This is the one I just bought to test:

        Yes. The Dri boxes seem a good idea. I hadn’t used EHU before and was a bit paranoid about using electricity whilst camping with my children so I went for a slightly different approach to an off the shelf EHU lead and ordered something bespoke before I read your article. I went to a company online called Tough Leads who will make you up any lead you want. So I asked for a 15m extra tough orange cable, a fused 4 socket strip, the correct 16A blue plug for camping hook up and a more sensitive inline 10mA RCD (IP66) close to the plug, a bit like you would get on a hot tub. That way the cable was RCD protected, not just the socket strip. I put the socket strip in a large dri box so everything was IP44 or better even in use. I used it the weekend before last and it worked great. I can store the cable in the Dri box when travelling or at home too. I think it is a safer set up although it did cost a bit more than an off the shelf hook up and took a little more organising too.

      I think it probably best to phone ahead. I would imagine there would be specific facilities for e-bikes. Let me know what you find out!

        Hi Matt thanks for the reply.
        I have made a few for some people close to me and use it actively.
        At the moment the device is quite expensive since all is made in a small batch (by hand) and all parts are for low volume (consumer) prices.
        Also it’s quite some work to build all the devices and I cannot make money with it at this point.
        Technology wise it can also be a bit better.
        I’m on the fence if I’m going to invest time and more effort in this…….. all depends on interest from people 😉 is a placeholder to see if I get responses from people.
        I think many have this wish but perhaps don’t feel the need enough to look for something like this 😉

        Thanks for your interest and keeping my reply on your website for now I don’t plan to make more then these few.

          No worries, Erik. I think its probably wise to do things the way you’re doing for now. I think the ideas cool but not sure how financially successful it could be? Depends on the price point. Manufacturing vs Cost is always the hard bit isn’t it!?

Any thoughts on this piece? I'd love to hear them :)
