How to install a wallbox: fuse box, grid notice, electrician

Your part of this job needs no tools. ABL's manual says a qualified electrical contractor must install the box and start it up. Alfen's says only a qualified electrician may install, commission or maintain its charger. So nothing below asks you to open a cover or touch a wire.

The steps come from the two manuals named below and Vattenfall's published process, with rules read November 2, 2026. None of it is my own experience of an install.

What to have ready

Do these before you ring anyone.

1. Photograph the meter label and the closed fuse box. ANWB's test: 220 or 230 V means one phase, and 3 x 230 V or 380/400 V means three. What that means for charging speed is worth reading first.
2. Pick a spot and measure. Vattenfall suggests about an arm's length from the car. ABL wants a level, firm surface of at least 262 x 222 mm.
3. Pace out the cable route from fuse box to parking spot, and note every wall or floor it crosses. Vattenfall names distance and wall openings as the things that drive the price.
4. List your big loads. Vattenfall names instantaneous water heaters and pools as loads that use up the connection's reserve.
5. Note the house's age. Vattenfall says homes built before 1990 may need modernising.

What the electrician does

Vattenfall describes two visits. On the first, a certified electrician checks the connection's capacity, the meter cabinet and the protection devices, then you get a quote within a few days. On the second, usually one day, the work runs like this:

1. Fit protection in the meter cabinet if it's missing.
2. Run the cable, opening walls where needed. Vattenfall suggests adding a LAN cable now.
3. Mount the box and test it.
4. Commission it and show you how to use it.

Vattenfall says each charging point needs its own circuit under DIN VDE 0100-722. It gives €600 to €3,000 as the usual installation range in Germany, more with groundwork or a new meter cabinet. That page dates from April 9, 2024, and Vattenfall sells this service, so read it as rough.

Reading the quote against the manual

These numbers aren't instructions for you. They're for checking a quote against the box.

The Alfen Eve Single S-line manual (V4.0, August 2024) advises, for 11 kW on three phases, a minimum 5 x 4 mm² cable up to an assumed 50 m, a 20 A three-pole type B or C breaker, and a 30 mA type A or B residual current device. It recommends mounting the bottom of the case 800 to 1,200 mm off the ground. The box is rated IP55, IK10. It costs €619 at The Mobility House.

The ABL eMH1 1W1101 manual (0301800_a) wants 140 to 160 cm from floor to the bottom edge, and that's higher than Alfen's range. Its specification lists a built-in type A residual current device with DC detection, so the electrician adds a separate type C breaker rather than another RCD. It also asks for a site out of direct sun and protected from rain. Its 6 m cable is fixed, at €439 from the same store. Both are German store prices, checked 2 November 2026, and they differ abroad.

The manual in your box beats my summary. My copy has no date and talks about changes from October 2018, ABL's data sheet for this model is revision 05/22, and The Mobility House says ABL has since revised the design. Check the mounting height and the light signal against yours.

The notice to the grid

These rules move, and each covers only its own country.

Germany (Bundesnetzagentur, read November 2, 2026). You must tell the grid operator about the wallbox before it goes into service, under section 19(2) of the NAV. Above 12 kVA, roughly 11 kW, you need approval, and the operator has two months to answer. The work must be done by the operator or a firm in its installer register. Some electricians handle the notice, so ask.

A box above 4.2 kW installed since January 1, 2024 also falls under section 14a. You report it, sign a control agreement and choose how you're billed. The operator may dim it, never below 4.2 kW. In return you get a lower grid fee: a flat €110 to €190 a year in the regulator's 2023 figure, or 40% of the grid energy price with a separate meter. The Mobility House lists the ABL as controllable through a potential-free contact, and the Alfen through that, an energy management system or OCPP. Ask your electrician and grid operator which one they'll use before you order.

There's no grant to plan on. 42watt, a secondary source, says in September 2026 that no federal money goes to wallboxes at owner-occupied houses.

France (Legrand, a maker, read November 2, 2026). Legrand says a private person may not install a charging point above 3.7 kW, and cites decree 2017-26 in requiring an electrician with the IRVE qualification. I couldn't read the decree itself. Legrand also says a private person may fit a point up to 3.7 kW. Here that stays the electrician's job too.

Netherlands (Rijksoverheid, read November 2, 2026). If you need a heavier connection, operators have ranked requests since July 1, 2026, and a charge point falls behind a hospital. Have an installer check that you need one first.

Italy (Tohmo, a charger seller, updated September 26, 2026). A meter upgrade goes through your supplier or distributor. An 11 or 22 kW box needs a three-phase meter.

Elsewhere, ask your grid operator.

When it's done

ABL's manual gives the sign to look for at handover: the green light flashes every 5 seconds when the box is ready. Alfen lists its own checks. Ask the electrician to walk you through them.

Still choosing? I'd pick the box after the first visit, not before. By then you'll know your phases and your cable length. The home charger list has prices side by side.
