Nowadays, homes are full of all sensitive electronics that are easily damaged by common power surges, spikes or voltage impulses. Your investment is not as safe as you think.
The cost of replacing electronics equipment in an average home is approximately $8000. This figure can easily top $20000 if the homeowner has a sophisticated entertainment system, or a home office.
Homeowners today needs more than power strips. It’s time to educate and teach them the complete home surge protection.
A lightning strike and electrical utility grid are accountable for only 20% of all surges experienced. They are external sources and typically larger and more catastrophic than internally generated surges.
A lightning strike has a maximum surge as 20000volts and 10000amps.
The other 80% of all surges and spikes originate in the home are internal sources:
A/C, furnace, clothes dryer, power tools, garage door, any motor load turning on & off. Just turn on the A/C or dryer can result a surge or spike that will overtime damage the electronics. If the surge doesn’t initially damage the electronics it will reduce its lifespan.
Internal and external surges are random and high energy. They are of short duration, typically 0.5 – 200 microseconds, too fast to be stopped by circuit breakers or fuses.
Lightning strike
Extremely high amount surge current from a lightning strike enter the home through the service meter connection and continue to flow through the entire home electrical system. Without any surge protection, all connected electronic equipment can be severely damaged.
Most homeowners lack the knowledge to protect electronic by only using surge strips. This only partially inadequate protects the equipments (FYI: The typical surge strip provides a surge current rating of only 2000 to 6000amps).
Now, don’t throw away your surge strips. They do provide vital protection for your electronic devices. But, surge strips alone can’t provide sufficient protection.
Again, the electrical surge enters the home and travel throughout the electrical wiring. The surge strip attends to divert the damaging electrical surge away from the sensitive electronic but the surge energy is too high and some devices can be damaged. This mentioned before is a partial protection.
Mapleleaf Electric Inc recommends that to fully protect your investment you should consider installing surge protections in a 2 stage approach (complete home surge protection).
Primary protection for service entrance
Stage 1 – Primary protection for service entrance (it’s a device that is directly installed to the electrical panel). The first surge protection device should be placed here to suppress a large percentage of the initial event. It will divert the initial high surge energy to ground, away from the rest of the electrical system and reduce the voltage surge to an acceptable level.
Secondary protection at point of use
Stage 2 –Secondary protection at point of use (e.g. surge strip) which should be installed just ahead of critical loads. This will deal with any residual voltage.
The remaining less destructive surge energy is now eliminated at stage 2 with surge strips. No damage will occur to the home electronic such as TV and computer.
Remember 80% are generated inside the home. Surge strips will manage any internally produced surge and stop any voltage run that may pass to the electrical panel surge protection. This complete surge protection is the most effect solutions to prevent your expensive electronic from damaging. It will offer a rapid response time that can shutdown the surge before any damage is done.
