The answer to 'flickering EV charger installation' is that a flickering or intermittent EV charger is often caused by a loose connection or electrical issue. This can happen during the initial installation or over time as the connections loosen. Symptoms include the charger turning on and off repeatedly or the charging status light flickering.
To troubleshoot, first check all the connections at the charger and the electrical panel to ensure they are tight. If that doesn't resolve it, the issue may be with the wiring or electrical supply. In this case, it's best to call a licensed electrician to inspect the installation and make any necessary repairs.
