Common Causes of Electrical Power Surges

EV Charger Precautions, Electrical Power Surges

Electrical power surges are sudden – practically imperceptible in their speed – and the damage they leave behind can be devastatingly expensive if your home is unprotected.

Common Causes of Electrical Power Surges

These surges are caused by both internal and external factors. The most common include:

  • Lightning strikes These are rare but highly destructive. They can cause:
    • Extremely high voltage spikes
    • Instant damage to electronics
  • Faulty or outdated wiring – Wiring faults are usually caused by frayed wires, loose connections, or poorly done installations. These wires can’t handle your home’s electrical load efficiently and can create irregular voltage flow that may result in:
    • Burn marks around your power outlets
    • A burnt smell
    • Buzzing from your outlets
    • Frequent tripping
  • High-powered electrical devices – Require a lot of energy, meaning they can cause a brief surge when they cycle on and off, which can damage sensitive electronics. Major culprits include:
    • Air conditioners
    • Refrigerators
    • Washing machines
  • Overloaded circuits – This is usually the consequence of your electrical system failing to handle the load that is demanded of it, which can cause overheating and voltage fluctuations. This increased demand can result from:
    • Multiple high-wattage devices on one outlet
    • Extensive cord overuse
    • Insufficient circuit capacity
  • Utility company issues – When they restore or adjust power, it can send a surge through the system. These surges are usually a result of:
    • Grid switching
    • Maintenance work
    • Sudden restoration after outages
  • Short circuits and ground faults – Can result from:
    • Damaged insulation
    • Exposed wires
    • Improper grounding
  • Power outages and restorations – One of the most common causes of electrical power surges. There are usually no safety issues while the power is off, but once your provider turns it back on, it can cause:
    • Sudden voltage spikes – Anything that doesn’t have a surge protector will be damaged by the sudden jump in current.
    • Simultaneous demand from multiple homes
    • Grid instability

How to Protect Your Home from Electrical Power Surges

  • Install whole-home surge protectors – Installed at your home’s electrical panel. Offers protection for all your devices and appliances. First line of defense against excessive voltage.
  • Use surge protector outlets – Designed to absorb high voltages and protect your appliances from surges.
  • Upgrade outdated wiring and panels – The wiring in your home needs to be able to handle your electrical needs.
  • Unplug sensitive electronics during storms.
  • Avoid overloading circuits.
