Surge Protection

Here is a few tips to look for in a good surge protector:

1. Response time should be less than 1 nanosecond.

2. Energy absorption/dissipation should be at a rating of 600 joules or more.

3. Clamping voltage should be 330 V to 400 V. Generally, a clamping voltage more than 400 V is too high.

4. Get one with a an indicator light that tells you if the protection components are functioning. All MOVs (Metal oxide varistors (MOV) are semiconductors that protect electronic components and systems from transient voltages) will burn out after repeated power surges, but the protector will still function as a power strip. Without an indicator light, you have no way of knowing if your protector is still functioning properly.

5. Get one that has self test function. A button you push to test it.

can I bypass energy smart panel on whirlpool water heater


Yes, you can convert to ordinary electric water heater by removing the electronic thermostat and lower thermistor, and installing generic mechanical thermostats:

The front panel control can also be unplugged, and the unit will work fine on the electronic thermostat.

Don't forget... all these modern electronic water heaters are susceptible to surge. Nearby lightning strike can blow them out. Install type 1 or type 2 surge protection in main breaker panel

110v surge protector that conserves power for freezer


A surge protector for a freezer is a good idea. To conserve energy? On paper it looks good but seriously only real savings are on bigger equipment.

What's the difference between a surge and a spike in voltage?


A spike is an increase in voltage for 1-2 nanoseconds.
A surge is the increase lasts 3+ nanoseconds.

my wii stopped working. the light is off. i tried unplugging and plugging everything back in twice. it was plugged into a surge protector, but the electricity did go out in my house today.



MysticMynstr: I know you already figured this out. But, you posted the solution as a comment and it will be easily missed. Also, the problem still shows with an unconfirmed solution.


Unplug the power adapter at both ends (at the console and especially at the power outlet). Give the capacitors at least a minute (perhaps longer) to completely dissipate residual energy. Make absolutely sure to wait long enough during power disconnection. Then, hook it back up and it should be good to go.

If the power light does not come back on, even after wait several minutes. The power adapter will likely need to be replaced. Any electronics shop will be able to test the power adapter first to be sure it is the problem.


I would give credit to someone else for this super simple solution. But, it's all over the internet.

have an fg5700ak runs ok but no power output what


Typical diodes are 10 amp for these. The stator and rotor both have VERY low resistance readings. The reading typically will be below that which will register MEANINGFULLY on the digital meters.

My generator had 10 amp diodes with surge protectors across them. One of the protectors shorted and generator output was zero. Mine is a 6KW diesel silent unit.

Replaced the diodes with 70 amp ones with surge protectors that have 20 times the energy absorbtion as the originals. Unfortunately this required some lathe work to make holders for the diodes and the surge protectors to ride on the rotor.

Used the light bulb trick to remagnitize it once diodes were replaced.
