Why You May Lose Power To One Part Of The House

Posted on: 15 March 2018

There are situations where you may lose power to one part of your house while the rest of the house still has power. Here are some of the reasons you may experience such a problem:

A Tripped Breaker

A tripped breaker is probably the most common reason part of a house may lose its electricity. The breaker is there to ensure that you don't suffer electrical shock or equipment damage due to unusually high current; it does this by cutting off power supply when the current exceeds the preset limit. Therefore, if the power is out in one section of the house, head to the breaker to see if it is tripped. If the breaker is tripped, then reset it and confirm if the power stays on. If the breaker trips again and you lose power to that section of the house again, don't reset the breaker again without diagnosing the problem.

A Triggered GFCI Receptacle

A Ground Fault Circuit Interrupter (GFCI) is also a safety design just like a circuit breaker; it also shuts off power when it detects that the power is flowing through the wrong conduit (for example, through a person). Though they perform the same functions, a GFCI is safer than a conventional circuit breaker because the former detects even the smallest power imbalance and reacts faster. This is why they are used to prevent electrocutions in places such as bathrooms or kitchens.

Therefore, if you are not getting power in a particular outlet or specific part of the house, check if you have a GFCI outlet and confirm whether it has tripped. Note that a GFCI outlet may not be installed near the electrical outlets or fixtures it controls, so you may have to check all your GFCIs. An accidentally tripped GFCI should reset; if it doesn't then it means there is a problem that needs to be fixed first.

Electrical Defect or Malfunction

In some cases, the issue might not be a GFCI or circuit breaker, but rather an electrical defect or malfunction. There are many areas where the flow of electricity may be interrupted. For example, it might be that there is a cable disconnection (maybe a pest chewed on a wire) or a repair wasn't properly done. In this case, your best bet is to consult a professional electrician.              

Electrical problems don't make good DIY projects; they mostly require a professional's input. Therefore, unless you know what you are doing or the problem at hand is really simple, let an electrician handle the problem. For more information, contact companies like McDonald Electric.
