    I just replaced my refrigerator and wanted to know what your opinions are about installing a receptical surge protector? Thanks:)

    Surge protectors work on very short duration ( microsecond ) transients. They do not do much for brownouts, or a roll up in voltage from the power company. Unless you have a foo-foo model that talks to you and plays mood music, etc.....then the refrig. is not likely to be damaged by spikes.

    More and more appliances have electronic controls verses mechanical, so it doesn't hurt. Panamax makes some nice ones. Behind a frig, though, the extra couple of inches could be a problem.

    P&S and Levition make outlet surge protectors. With alarm and led indicators.

    I would give you the number of the unit I got but I don't have it. It was hospital grade.

    Except the pocketbook.
    I've never seen data on what you can expect as to equipment protection before and after you install a protector. I think it is mostly snake oil.

    But massive protection is recommended for Florida, they have many lightning strikes.

    Surge protection is highly recommended for protection from transients a prefered method would be to install a TVSS at the panel and one at the point of use. This minimizes destructive forces from impulses that may be imposed on the system.


    While there are some peddling snke oil out there TVSS's when properly installed are not in that list.


    As for a refrigerator as noted most/all newer appliances have electronics in them my kitchen alone has clocks micro wave, stove, dishwasher and clock

    The key to lightning protection is good bonding. People think that having a perfect electrode is important. It isn't.

    I would have more than just a little tvss installed on your mains, I would also have a multi mode surge suppressor installed on the phone and coax. Make sure that all coax and phone grounds are bonded to the main system ground. A ground rod will NOT do.

    Do you have any clue as to what you are saying?

    Just what do you think bonding is doing?

    You make this statement, “grounds are bonded to the main system ground.”

    Just what is the system ground?

    Is it not the electrode?

    Then I suppose that statement kills your opening statement of, “People think that having a perfect electrode is important. It isn't.”

    Just for the record one of the reasons for installing an electrode is to dissipate lightning.

    Jesus!:confused:

    Relax. . . :p

    The OP can and should decide what to believe.

    Yes I agree that the original poster can believe what he wants to believe but I also believe that he should have the complete facts to make his assessment on before making a decision.

    The grounding electrode is installed for four reasons.

    250.4
    (A) Grounded Systems.
    (1) Electrical System Grounding. Electrical systems that are grounded shall be connected to earth in a manner that will limit the voltage imposed by lightning, line surges, or unintentional contact with higher-voltage lines and that will stabilize the voltage to earth during normal operation.

    Bonding on the other hand is done for a different reason,

    250.4(A) (3) Bonding of Electrical Equipment. Normally non–current-carrying conductive materials enclosing electrical conductors or equipment, or forming part of such equipment, shall be connected together and to the electrical supply source in a manner that establishes an effective ground-fault current path.

    The bonding of equipment is NOT done for lightning but the grounding electrode is installed for lightning.
    Bonding is done to facilitate the operation of the overcurrent device (the breaker or fuse) and has no role in a lightning strike

    So easy there, lighten up a little, learn a little something but make sure that what you learn is correct and not some opinion of someone that has displayed a complete lack of knowledge. Learn to believe the truth not half baked ideas form the uninformed, unknowing and those who have little or no knowledge.

    EDITED TO ADD

    Sorry That Guy
    After making this post I got to thinking maybe I should look at your profile so I came back to see where you fit into the electrical trade.

    I see by your profile that you haven’t had any formal training in the electrical field or at least you didn’t mention any in your profile.
    This helps me better understand that you wouldn’t know what I was talking about either unless you take the time to research a little to see which is correct.

    The comment made by rgsgww concerning the electrode having nothing to do with a lightning strike is so far off base that it isn’t even in the same ball park.

    The grounding electrode is the ONLY thing that plays a role in a lightning strike.

    Bonding is what makes the fuses and breakers work. Bonding is done to ensure that there is a low impedance path from every non-current carrying metal part all the way back to the center tap of the utility transformer. The connection to earth will not make a low impedance path back to the center tap of the utility transformer to operate the overcurrent devices.

    Earthing does make a path between the electrical system and the earth. During a lightning strike current is trying to complete a path between the cloud and earth. Should the electrical system be in that path we want to ensure that a path is established that will divert the current to earth instead of throughout the electrical system. Therefore we install an electrode that connects the system to earth.

    An electrode is the most important, but I meant that it is important to keep all electrodes connected together. And not to just install a bunch of separated electrodes.

    I did get some of my terms messed up. Bonding is done to clear faults, I know that. I used "bonding" as in connecting the electrodes together. Which is the wrong word to use.

    Main system ground, that is the water pipe, ground rods for the service panels, etc.

    Most of what you say in this post is true except for the "main system ground". There is no such thing as the main system ground. All electrodes present MUST be bonded together to form ONE electrode system.

    250.50 Grounding Electrode System.
    All grounding electrodes as described in 250.52(A)(1) through (A)(7) that are present at each building or structure served shall be bonded together to form the grounding electrode system. Where none of these grounding electrodes exist, one or more of the grounding electrodes specified in 250.52(A)(4) through (A)(8) shall be installed and used.


    The key word in that section is "the" meaning only one.

    Once again I've used the wrong words..."the".

    Anybody reading this for electrical help, please read jwelwctric's posts. Mine can be taken the wrong way.

    I wouldn't say that you are wrong in the way that you think.

    The concept of connecting to earth has been misunderstood for many years and the misconceptions have been past down generation after generation.
    Even the code was used to lead these misconceptions.

    Read the Fine Print Note from the 1984 code cycle
    [​IMG]

    The equipment grounding conductor does just as its name implies. It connects the non-current carrying metal parts to earth.
    The Main Bonding Jumper installed in the service equipment bonds these conductors that are used to connect non-current carrying metal parts to earth to the grounded conductor of the service entrance conductors. Solidly grounded was accomplished with the main bonding conductor but the language was interpreted to mean that it meant connected to the grounding electrode system due to the verbiage above the last sentence. This is what makes the breakers trip and the fuses blow in the event of a ground fault.
