A loose neutral (grounded conductor) will cause several problems which do include flicker, pulsing, and diming lights. The main effect is excessive heating at the loose termination that will be responsible for insulation damage, and circuit voltage drop.
What are the effects of a loose neutral wire?
Circuit Breakers and Loose Electrical Wires
- Dangers of a Loose Connection. Wires connect to outlets—properly called receptacles—with screw terminals or other devices to provide a secure connection.
- Loose Wires Can Cause Arching. ...
- Breakers Don't Always Catch Bad Connections. ...

Can a power surge cause a loose neutral?
Will a loose neutral cause a power surge? In most cases, a bad neutral connection causes spikes in voltage. If you find that these surges are occurring all over the house, you could have a problem with the meter socket, the panel, or the utility connections.
Should neutral wires be bigger than live wires?
When your three phases are not balanced or you have a lot of non-lineal charges ( like computers) the current on the neutral wire is higher than that on the live wires. So yes the neutral wire should be wider, but calculations must be carried out to determine this. Always
How do you know if a neutral wire is loose?

And then move away from it to each of the other outlets.
Can a loose neutral cause voltage drop?
Senior Member. A loose neutral (grounded conductor) will cause several problems which do include flicker, pulsing, and diming lights. The main effect is excessive heating at the loose termination that will be responsible for insulation damage, and circuit voltage drop.
What happens when you lose neutral?
If the neutral wire is broken or disconnected, the out of balanced current cannot return to the supply through the star point, but it must return. So, this current takes the path back to the supply through the lines.
What happens if neutral fails?
If a neutral wire gets disconnected, then the appliances will not work, the fan may get burn, choke in the tube may burn, and current starts flowing through the neutral wire.
Why are my portable heaters brown?
The wattage of the portable space heaters isn't really enough to give you the brown power that you are experiencing (provided that the incoming lines are the proper gauge for the load/run). Low voltage will also not cause the flickering lights that you see - they should just dim (as if controlled by a dimmer). Even the satellite receivers shouldn't be that affected by low voltage (the main circuits are behind a transformer - rectifier setup) and even with the low voltage, would probably remain in regulation.#N#I don't believe that your problem has been discovered yet.
Can satellite receivers be affected by low voltage?

Why is my wire connection loose?
By far the most common problem is when screw terminal connections at wall switches and outlets become loose. Because these fixtures get the most use within an electrical system, these are the places to look first if you suspect wire connection problems. Loose wire connections at a switch, outlet, or light fixture are often signaled by a buzzing ...
How to fix a wire connection error?
To fix the problem, first, turn off the power to the circuit. Then, remove the electrical tape from the wires and clean them. Make sure there is the proper amount of exposed wire showing (for most connectors, ...
What gauge wire is used for a 15 amp circuit?
Note: Make sure the pigtail wire is the same wire gauge as the circuit wires. A 15-amp circuit normally uses 14-gauge wire; a 20-amp circuit uses 12-gauge wire.
What happens to wires when they are plugged in?
Every time a switch is used or appliances are plugged in, and the natural result of all this usage is that wire connections can loosen over time.
What is exposed wire?
It is quite common, especially with amateur electrical work, to see a screw terminal connection or wire nut connection where it has too much (or too little) exposed copper wire showing at the wires.
Where should wires be wrapped?
Wires should be wrapped clockwise around the screw terminals; if they are reversed, they can be prone to loosening. With wire nut connections, all of the bare copper wire should be hidden under the plastic cap, with no exposed wire showing at the bottom of the wire nut.
Is there a danger from a loose wire connection?
Your electrical system has a lot of safeguards against danger from bad wire connections, such as its grounding system, its circuit breakers, and GFCI and AFCI protection. Still, there is danger from sparking and arcing whenever there is a loose wire connection in your system.
