There is no hard code-mandated maximum distance for an EV charger from the electrical panel, but distance directly affects installation cost, wire sizing, and performance. Longer runs are absolutely possible, they just involve more material and, in some cases, larger wire to prevent voltage drop. Here is what to know, from the licensed electricians at EZSMART, serving Toronto and the GTA.
For detached garages or long runs, installing a subpanel closer to the charger location is often more cost effective and flexible than running a single very long circuit. A subpanel from a manufacturer like Eaton or Square D also supports future additions in that area, such as workshop outlets or additional charging stations.
A licensed electrician assesses the intended location, calculates the required wire size accounting for voltage drop, and provides a quote that reflects the actual scope. Work should follow Electrical Safety Authority standards.
Is there a maximum distance for a Level 2 charger?
Not a hard maximum, though very long runs may require larger wire and a subpanel becomes more cost effective.
Does distance affect charging speed?
Only if voltage drop is significant, which is why proper wire sizing matters for longer runs.
Can I run wiring underground for a detached garage charger?
Yes, with proper conduit rated for underground use, and typically with a subpanel at the garage.
