There is no single clearance number that applies to every charger, and any source that quotes you one universal figure is guessing. The clearance for your installation lives in two documents: the charger maker’s installation instructions for the exact model, which set the space the unit itself needs, and the working-space rules of the electrical code your installer works to, which set the space a person needs in front of electrical equipment. Your installer’s job is to satisfy both on your wall.
Key Takeaways
- No universal clearance figure exists — anyone quoting one for every charger is guessing.
- The manual for your exact model sets the unit’s clearances; the local electrical code sets working space.
- Clearance serves three jobs: servicing the unit, room for the cable, and space for a person to stand and work.
- Mounting height is a separate question with its own answer in the same documents.
The Two Documents That Own the Numbers
| Source | What it sets | Where you get it |
|---|---|---|
| The maker’s installation instructions | The unit’s own clearances: room to open and service it, space for the cable to hang and reach, and positions the maker rules out | The manual for the exact model — supplied with the unit and usually published by the maker |
| The electrical code in force locally | Working space around electrical equipment, so the installation can be inspected and serviced safely | Applied by your licensed electrician under the adopted code — NFPA 70 in the U.S. — and checked at inspection |
| Building and parking rules, where they apply | Bay layouts in shared garages: where a unit may sit relative to the parking space and the driving lane | The building’s management and the local permit process |
Notice what is not on the list: a blog post, a forum answer, or a different charger’s clearance. Two similar wallboxes can carry different instructions, because the manual is part of how that unit was tested and listed.
What the Space Around a Charger Is For
Understanding what clearance does makes the manual’s requirements easier to respect rather than work around:
- Servicing. Covers come off and connections get inspected. A unit boxed into a corner cannot be serviced in place, which turns a small job into a removal.
- The cable. A charging cable needs somewhere to hang, a bend it can make without strain, and a path to the car’s inlet. Space beside the unit is cable space, not wasted wall.
- People. Working space in the code exists so a person can stand at the equipment properly — the same logic applies when you plug in at night and walk past the parked car.
- Air. Chargers shed modest heat into the room while they work. They are designed for open air on a wall; wrapping or cupboarding a unit works against that, as our enclosure guide sets out.
Clearance Is Not Mounting Height
Height is the neighbouring question, and it has its own answer in the same two documents — the manual states a mounting position for the model, and accessibility or building rules can add theirs in shared spaces. Our guide to how high an EV charger should be mounted covers that side. Keep the two apart: a unit can sit at a sensible height and still fail on the space around it.
How EVDANCE Units Handle It
The EVDANCE EV-ACT5006T wall charger (up to 48 A, NACS, 25 ft cable, IP65/IP66) is installed to the clearances in its own instructions, which your electrician reads before the wall is drilled; that document is the specification for the job. A portable such as the EV-ACS4005T (9.6 kW, IP66) asks for less: a hook or shelf that keeps it off the floor, reachable, with its cable free to drape — the same sourcing logic at a smaller scale. Compare both on our residential charging page.
Frequently Asked Questions
Can I install storage shelves right up against the charger?
Only if the manual’s clearances still hold with them in place. Stored items against the unit block servicing and airflow. Measure against the manual, not against what fits.
My installer left less space than the manual says. Is that a problem?
It is worth raising. The installation instructions are part of the basis on which the unit was listed and its warranty written, so an installation that ignores them is the installer’s to reconcile — ask them to, and keep the exchange in writing.
Does a charger in a shared garage need different clearance?
The unit’s manual does not change, but the building layer is added: bay layout, the driving lane and the building’s own rules all bear on where the unit may sit. That is settled in the building’s approval and the permit, not by the installer alone.
