Your house might look beautiful and modern on the outside, but what is the situation like inside your walls? If the electrical wiring in your house is old and outdated, this can present a risk for fire and other safety hazards.
For example, some older homes might not have grounded outlets or GFCI protection where necessary. This poses an electrocution hazard, and should be resolved as soon as possible.
It is also possible that it might be aluminum wiring. Aluminum will become defective faster than copper, and in some cases, aluminum wiring can pose a fire hazard. You can identify it by looking for the word Aluminum or an abbreviation of it listed on the wire.
If you find that your home is wired with aluminum, your best option is to contact an electrician who can give you options for adapting your system to minimize risk or rewiring your home.
