Just to try and clear a few things up re the safety concerns of Easee chargepoints:
The safety issues which led to the Swedish authority for electrical safety to imposed a sales ban on Easee chargers, has very little to do with the fitment of a current clamp or any other box.
The sales ban follows several tests carried out by the Swedish Electrical Safety Authority earlier this year which revealed numerous safety deficiencies in the wall-mounted charging stations of the Norwegian manufacturer. One of the central problems: Contrary to the declaration, no RCD was installed, which did not meet standards.
The problem is that the Earth leakage circuit breaker may not always trip when and how it should:
Easee has used an electronic earth leakage circuit breaker solution instead of an electromechanical one. There is a risk that the earth leakage circuit breaker does not always trip when and as it should according to the Swedish Electrical Safety Authority. A charging station must also have DC protection to ensure the earth leakage circuit breaker works properly. In the opinion of the authority, this is not the case.
Easee respnded saying it does not rely on a separate device mounted on a DIN rail but a system “integrated into the overall design of the charger”. If the built-in sensor detects AC and DC faults, the system triggers and is supposed to immediately cut off the power supply, which in Easee’s interpretation, ensures the function of an RCD!
On 22nd February this year Easee put out an international statement explaning how their eltronic RCD works:
This is how our RCD works
Easee’s charging robots have a built-in RCD that tests itself at least 365 times a year, so that you never charge without ground fault protection.
Safety is at the very top of the priority list when we develop new products. And we get the help of independent third parties right from the planning stage to ensure that the components we use are fit for purpose.
One of the most important factors in safeguarding the safety of an electrical installation is that you have sufficient protection against ground faults.

One area I picked up on is, there is no mention in milli seconds on how long the RCD should take to cut the power supply – this should happen within 30ms, Although it is quoted in the UK installation guide
“One of the most important components of our charger is the RCD. This protection has two tasks: The first is to detect leakage current from the current conductors to ground. The second is to cut the power supply to the affected plant parts. This must happen so quickly that the current does not have time to cause damage before it is disconnected.”
Easee has also quoted in its installation guide:
“The integrated RCD has no influence on the function of
external protective devices. If a Class II installation is
supplying the Charging Robot(s), an RCD device is not
required to protect Easee One. The decision to install
an RCD upstream of the Easee One should be taken in
accordance with local wiring regulations”
Important – As per rge regulations posted earlier 99% of UK chargepoint installs, have a RCD fitted upstream of the actual charge point itself. This does not rely on any internal RCD that may be fitted internally or part of the chargepoint itself. Therefore as of current regs Easee chargepoints are not banned in the UK and are approved fr sale as normal. If you have had an Easee charger installed in the UK after the 29th of June 2022, you should have received a State of compliance.
