Electrical โ FAQ
Do I need an electrician to install a dimmer switch?
Most homeowners can install a dimmer in 15-30 minutes using basic tools. Turn off power at the breaker, follow the included wiring diagram, and use wire connectors. If your box lacks a neutral wire for smart dimmers, consult an electrician.
Why do my LED bulbs flicker on a new dimmer?
Flickering indicates incompatible bulbs or insufficient load. Use dimmer-rated LEDs from Philips, Cree, or GE. Ensure total wattage exceeds the dimmer's minimum load (usually 10-25W). Try swapping bulb brands or adding one more bulb to the circuit.
Can I use a dimmer switch on a ceiling fan?
No, dimmer switches are not rated for motor loads and will damage fan motors. Use a dedicated fan speed controller instead. Dimmers only work with compatible lighting loads.
What's the difference between single-pole and 3-way?
Single-pole controls lights from one location. 3-way uses two switches controlling the same light (like staircases). Buy 3-way dimmers for multi-location control; they work in single-pole mode too.
How many LED bulbs can one dimmer control?
Divide the dimmer's LED rating (typically 150W) by each bulb's wattage. A 150W dimmer handles thirty 5W LEDs. Stay under 80% of maximum rating to prevent overheating and extend lifespan.
Are smart dimmers worth the extra cost?
Smart dimmers pay off if you want scheduling, remote control, or voice commands. For basic dimming, manual switches perform equally well at half the price. Consider your tech comfort level and Wi-Fi reliability.
