Ratio Electric Home Box is a charging station for up to 7.4kW which is developed for private and semi-private use. The charging station offers ease of use and safe charging in accordance with regulations (IEC 61851).
Practical and Universal Solutions
The Home Box charging station enables mode 3 charging and can be supplied with a 5 or 10 meter fixed charging cable with type 2 plug. A fixed charging cable makes charging the car convenient and easy. Likewise, the charging station can also be supplied with a type 2 connector/ outlet, which makes it flexible- capable of charging all plug-in hybrids and electric cars safely and quickly. This is something we generally recommend, as it is a universal solution that all cars can use.
User Friendly
The charging station also has that option of adjusting the charging current between 6/8/10/12/14/16/20/24/28/32A in case the need arises. This is easily done via a button found on the front of the charging station. There is an option to get a built-in kWh counter which is practical to document power consumption or if you just want to see how much energy has been used
RCD-DD / DC-RCM (Residual current module)
New regulations (NEK 400:2018-722 norm) require that all new current courses that are to be used to charge electrical vehicles must have an earth fault circuit breaker type B or equivalent DC protection. The charging station has an integrated DC-RCM module of 6mA which takes care of the DC protection and means that you do not need earth fault protection type B installed in the fuse box.

According to regulations on electrical equipment §21, we are obliged to inform our customers that all electrical equipment intended to be part of a fixed electrical installation can only be installed by an authorized and registered installation company installasjonsvirksomhet.
Use ladeguiden (our charging guide) if you are unsure if this product suits your plug-in hybrid or electric car.

Questions and Answers
Do I have to have earth fault protection Type B on the current course if I install Ratio Home Box with DC-RCM?
What is a supply cable?
A supply cable is a short cable where one end is mounted in the charging station and the other end is an industrial plug. It allows you to connect this directly to an industrial socket.
