When and How Should a Surge Protector Be Used on a Fixed Switch?


Common Causes of Lightning Strikes
  • Outdoor network cables or power cables are routed overhead.
  • A switch is deployed outdoors but is not properly grounded.

Damages of Lightning Strikes
  • If power cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn the power supplies.
  • If network cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn interfaces of the switch.
When a switch undergoes lightning strikes, overvoltage is induced by lightning on network cables and transmitted to interior of the chassis. The surge protection measures, such as lightning rod and chassis grounding cannot prevent the damage. Therefore, surge protectors or surge protection circuits are recommended.

Surge Protector Use Precautions Take the following precautions to protect a switch from lightning:
  • Ensure that the ground cable is connected to a ground bar or a ground point on the cabinet.
  • Avoid routing cables overhead in an outdoor environment. Bury cables underground or route them in steel tubes.
  • To protect network interfaces against lightning, use 8-line surge protectors (or Huawei certified 4-line surge protectors).
  • When installing a network interface surge protector, connect the IN end to terminals and the OUT end to network interfaces of the switch.
If a fixed switch is installed in a network box, follow these instructions:
  • Connect the ground cables of the switch and surge protectors to the ground bar in the network box.
  • The maximum length of a ground cable cannot exceed 40 cm, and a length of smaller than 15 cm is recommended.
  • If the network box is located outdoors and power cables are routed aerially over a long distance (more than 300 m) to the network box, it is recommended that you install a power supply surge protector in the network box. The decoupled power cable must be at least 3 m long

During a lightning storm my TV went off and won't come back on.


It's called a "power surge," and the only way you can prevent a power surge from destroying a television completely is to use a SURGE SUPPRESSOR, and make sure that the grounding for your electrical system is optimal (meaning at least THREE TRUE GROUND POINTS, usually GROUNDING ROD, GROUND MESH, and PLUMBING GROUND). Consult a qualified electrician.
Sorry for your loss!

Lincoln ac/dc 125/225 stray voltage question.We changed the aluminum transformer out for an older copper one because it was weak and the ground would bite you.


The shock can be caused by numerous issues such as high humidity, bad ground connection at the case, etc... the suppressor board is just another name for a surge protector, if it is bad, it could bleed current through the ground clamp

it may have taken a surge of power and fried one of the amps inside nothing to do but replace it. make sure that your main cable line to your house is grounded very good to a good earth ground source like a ground rod or gas line or cold water line.

you sure your engine isn't surging... you would see it at lower speeds... my motorcycle surges at a certain rpm due to fuel ratio's at the one speed ( running lean )... so what i am saying is, could it be that the engine surge only shows itself at a certain ground speed.

or is it because of a hydro system pressure relief valve ???

Rod sticking


make sure you have a good enough ground on your work-piece. try putting a chunk or strip of metal on or closer to your work-piece to get better current.

Power surg cannot get washer to power onnow


You may have damage to the control circuit board.
If it's still under warranty call the MFG.
Before you use it again check the ground on the circuit the washer is plugged into. If your in your home, go outside to the electrical meter.
Look around on the ground under the meter for a ground rod sticking up a few inches. Clean the grass away and see if the clamp that holds the wire to the rod can be wiggled by hand. If it's loose get it tightened. It the clamp is busted or the wire is cut or loose. Call an electrician to have it fixed. Also ask the electrician to check if the plumbing is grounded. Bad ground connections make power surges worse.
