Outdoor Wiring
A common mistake that some people make is in believing outdoor wiring and indoor wiring are the same thing when they are not. Electricity is not something to play around with, and the outdoor environment can quickly change a severed wire into a death trap. So when inspecting your house you should look for damaged plugs, lighting fixtures, cables, and improper wiring.
You should inspect your outdoor electrical no less than once a season, but preferably more, especially if you have kids. So make sure your cables are in good condition, always wear shoes to ground yourself when working with electrical equipment, and hire an electrician to fix any problems you may come across.
