Is it easy to install a dimmer switch?


Generally speaking, a homeowner can install dimmers. Though, there are a few instances where you should bring in professional help.

  • You should check the amperage of the circuit and the wattage of the new dimmer. If the amperage isn’t high enough to cover the wattage of your switch, you will need an extra wire run from your circuit breaker. The best option, in this case, is to hire a licensed and qualified electrician.
  • A couple of other thoughts before you dig into this switch project is that many older homes don’t have high-temperature insulation, which is demanded by many ceiling light dimmers and fan dimmers.

Most homeowners should never try DIY electrical work unless they already have knowledge in the electrical field.

An amateur electrical job may produce bad wire connections, overloaded circuits, and faulty grounding, which could be hazardous to the safety of your home.

Licensed electricians must undergo thorough training and keep up to date with the latest electrical regulations.
