Campervan Electrics Plymouth Devon: The Shocking Reality of Poor Wiring in Van Conversions

The side of van life you don’t see

There’s a side of van life you don’t see online. No sunsets, no surfboards, no coffee on a mountain view. Just melted cables, burnt connections and overloaded systems hidden behind panels.

At Colebrook Transporters in Plympton, Plymouth, we see it first-hand in our workshop. Over the past few weeks, more and more campervans across Devon have come through our doors with electrical installations that are not just poorly done, but genuinely unsafe.

This is not about neatness. This is about safety.

What we are finding in campervans

These are not isolated cases. This is what we are regularly seeing:

• Melted electrical connections
• 2000W inverters wired with cables far too small for the load
• Loose and poorly secured wiring
• Live cables left exposed behind panels
• Incorrect cable sizing throughout systems
• Fuses that are incorrectly rated or not protecting circuits properly
• Crimp connections held together with cable ties

Every one of these faults has the potential to cause serious damage.

Why poor wiring is a real risk

A campervan is a confined space. Your electrics run behind furniture, inside units and under flooring. If something starts to fail, heat builds quickly and there is very little room for error.

High demand components such as inverters place a heavy load on a system. A 2000W inverter will draw a significant current. If the cable supplying it is undersized, it will heat up under load.

That heat builds, weakens connections and can lead to failure.

Electrical faults are now one of the most common problems we see in van conversions across Plymouth and Devon. In the worst cases, they present a genuine fire risk.

The difference with a proper installation

A safe campervan electrical system is designed, not guessed.

It is not just about getting power from a battery to a socket. It is about ensuring every part of the system is working safely under load.

That includes:

• Correct cable sizing based on load and cable length
• Properly rated fuses protecting each circuit
• Secure connections that can handle vibration from driving
• Safe routing of cables away from heat and sharp edges
• Installation that meets current safety standards

When these fundamentals are right, the system is safe, reliable and built to last.

DIY campervan electrics

There is nothing wrong with building your own campervan, but electrics need to be approached properly.

If you are installing your own system:

• Use trusted tools such as the Victron Toolbox app
• Follow manufacturer instructions carefully
• Do not guess cable sizes or fuse ratings
• Avoid shortcuts
• Have the system checked once complete

Electrics are not something to piece together as you go.

Why regular checks matter

Even a professionally installed system should be checked over time. Vehicles move, vibrate and wear differently to a house.

Connections can loosen and components can degrade.

A yearly habitation service is one of the best ways to ensure your campervan remains safe, compliant and working as it should. Our motorhome habitation checks in Plymouth (https://colebrooktransporters.co.uk/motorhome-habitation-checks-plymouth-colebrook-csc-transporters2/) are designed to inspect both electrical and gas systems, giving you complete peace of mind that everything is safe and up to standard.

Whether your van is newly converted or has been on the road for years, regular checks are essential.

Campervan electrics in Plympton, Plymouth and Devon

At Colebrook Transporters, we carry out campervan electrics and full van conversions from our workshop in Plympton, Plymouth, working with customers across Devon.

We are an AWS Approved Workshop and our gas and electrical systems are installed by NCC trained technicians. We also inspect and test existing systems, whether newly installed or part of an older conversion.

If you are unsure about your setup, we are always happy to help and offer proper advice. We can also carry out a full motorhome habitation check in Plymouth to make sure your electrical system is safe and compliant.

Final word

A campervan should give you freedom, not problems.

If you are not completely confident in your electrics, it is worth getting them checked.

It is always better to deal with it early than to deal with the consequences later.
