The answer to 'EV charger dimming lights' is that it is a common issue that can be caused by several factors. The most common cause is an electrical overload on the circuit from the EV charger, which can lead to dimming or flickering of nearby lights. This is often due to the high power draw of the EV charger, which can exceed the capacity of the electrical circuit.
Other potential causes include loose or faulty wiring connections, issues with the EV charger itself, or problems with the home's electrical panel. In some cases, the EV charger may need to be upgraded or the home's electrical system may need to be adjusted to handle the additional load.
