Guide for purchasing surge suppressors for home use – Information to follow

Buying a complete home network filter is not an easy task given the variety of models available on the market today. Nevertheless, we have included you in all these reports on domestic surge protection systems.

Find out how to easily choose a high quality arrester for your home without sacrificing price or cost.

  • Type– Before purchasing a model, familiarize yourself with the different types of surge protections. You can choose any one of them according to your needs and your knowledge of the operation of each program.

Surge protection can protect multiple devices at the same time, while power point or house-wide surge protection protects the entire electrical system from external surges.

The wall-mounted surge protector has no cables or plugs directly into the socket close to the wall. Like the uninterrupted power supply system, your devices are equipped with a safe backup battery for continuous operation, even after an surge, interruption or immersion in water.

  • Check the number of ports –Never forget that every network filter has the same number of ports, some have six and some have twelve. It is therefore essential to buy one of the ports with the right number of ports to avoid loopback network security.
  • Think about the devices you want to connect to– Always buy the right surge protection for your electrical equipment. You can always count on quality, but your TV needs a different kind of protection than your lamp.
  • Caution for Certification– Make sure your power supply is UL certified and complies with UL 1449, which is a temporary surge protector. This way you can be sure that your equipment is protected as prescribed.
  • Control of energy absorption coefficient and terminal voltage– The energy absorption coefficient is the amount of energy a lightning conductor can absorb before it fails. The top is always better, preferably 6-700 joules or more. The clamp voltage is the voltage that makes it possible to wake up and absorb energy. It should be about 400 volts or less.
  • Response time is the time in nanoseconds required to activate the surge protector. A nanosecond or less is better.
  • Main Functions– This high quality, complete house line filter includes important functions such as timers, LED indicator, remote control for easy operation, GFCI protection to prevent electrical fire in case of short circuit and energy saving functions.
  • Warranty You should know what is under warranty and what is not. Indeed, certain guarantees apply to the devices connected to the surge protection in the event of a failure of the latter. Also think about how to submit an application if it does not work as expected.

Preparation phase for the installation of surge protection devices

  • First of all, you need two blank spaces on top of each other in your main panel to connect the SPD barrier. In the same way, you can use an existing 240-volt two-pole circuit breaker, but only with a rated voltage of two conductors. You can always contact the manufacturer’s technical support to verify this.
  • On the other hand, if the circuit breakers are not spread for two wires and you don’t have free space in the main window. All that is then required is the purchase of an surge protector (OSD), which is installed directly in the meter housing.
  • No matter how you disconnect from the main switch, there are always live wires that can kill you with the push of a button. So get to know them well and find a way to protect yourself from them before you unscrew the main panel.
  • Do not wear jewellery or rings when installing the do-it-yourself surge protector.

Systematic over-voltage protection Installation process

  • Main panel offset end cap protection

Pull the plug out of the socket and place a cardboard protector in the plate to prevent contact with live wires. Remove the two separators directly below the operational isolating switch. Then move them with the other wires they fall into to another part of the plate.

Protection against voltage surges, SPD mains to main switchgear in addition to two free spaces in the main switchgear. So the wires can get in. You can then connect the offset fitting to both the SPD and the main panel. Attach the EPD to the wall with a few screws.

  • Connect neutral conductor and protective earth (PE) to bus.

Connect the SPD wires to the main panel. Then remove the ¾ inch insulation from the neutral/white and grounded/green wires before laying them down and attaching them to the individual screw terminals closest to the neutral.

Make the bends as stable as possible by keeping all green, white and black wires short.

  • Cut the black wires and install.

Mark the two black wires of the EPD, then cut them to length and remove the insulation. Then insert the stripped wires into the breakers and secure them firmly.

  • Installation of surge protection on telephone and cable

Find a box demarcation service outside your home and route lengths of the phone cable through the SPD phone line connections. Then connect the home phone lines to the output terminals. Follow the same procedure to protect cable TV lines from voltage surges.
