May is National Electrical Safety Month, and here at Trico, we think it’s a great time to look around your home and check for potential safety hazards.
Power strips with surge protectors can help safeguard expensive equipment like televisions, home entertainment systems and computer components from power spikes. Voltage spikes are measured in joules, and surge protectors are rated for the number of joules they can effectively absorb. That means if your surge protector is rated at 1,000 joules, it should be replaced when it hits or passes that limit. When the limit is reached, protection stops, and you’re left with a basic power strip.
Some surge protectors include indicator lights that flicker to warn you when they’ve stopped working as designed, but many do not. If your electrical system takes a major hit, or if you don’t remember when you bought your surge protector, replacement may be the best option.
If you use extension cords regularly to connect devices and equipment to your wall outlets, you may live in an underwired home. With a growing number of electrical devices, having enough outlets in just the right spots can be challenging. Remember, extension cords are designed for temporary, occasional or periodic use.
If an extension cord gets noticeably warm when in use, it could be undersized for the intended use. If it shows any signs of frayed, cracked or heat-damaged insulation, it should be replaced. If the grounding prong is missing, crimped or loose, a grounded cord will not provide the protection designed into its performance. And always make sure that extension cords used in outdoor or potentially damp locations are rated for exterior use.
