Will an overloaded circuit cause lights to flicker?

Persistent and harsh flickering tends to be a sign of circuit overload. You should be cautious when using your circuit breaker if this is the case.
Why do my lights dim when I turn on the dryer?
When you turn on a dryer, it draws so much power, that it drags down the voltage, causing the light on the same circuit to dim. Sometimes you might notice a dimming of the lights, even on other circuits. It doesn’t take much of a dip in voltage to make a noticeable dimming of some lights.
Why are only some of my lights out?
Lights Out, Circuit Breaker Not Tripped One culprit could be a GFCI (Ground Fault Circuit Interrupter) outlet that has tripped. Other issues can include loose wiring or outlets. Over the years, wiring and screws can come loose. One outlet going out can impact multiple outlets or lights throughout the house.
Why do the lights dim momentarily when the refrigerator motor comes on?
When a motor, any motor, starts up it requires about twice as much electricity to get started than it does to keep turning.

How do you tell if you are overloading a circuit?
Signs of Overloaded Circuits The most obvious sign of an electrical circuit overload is a breaker tripping and shutting off all the power. Other signs can be less noticeable: Dimming lights, especially if lights dim when you turn on appliances or more lights. Buzzing outlets or switches.
Why do lights dim when heater turns on?
The current draw of a heating appliance can cause some instances of lights dimming. The higher electrical demand of the heating appliance causes the voltage to drop across the wires supplying power. The lights dim because there is less available voltage.
