    Default Whole House Surge protector

    Hi,

    I'm looking to install a whole house surge protector in my 150 amp panel. I remember an electrician telling me that the panel is at max capacity despite there being a few open slots.

    Slots 2 and 4 (hopefully "slots" is the right term for it) are currently open, which I believe would be the right location to install the whole house surge protector. My question is, can I even add the surge protector if the panel is already maxed out? I have no idea how this all works.

    Any advice will be greatly appreciated!

    Thanks!

    Dave

    The surge protectors don't draw any load ( very very little only to power up the LED status lights ) . The only thing adding the surge protection would contribute is filling the two remaining slots ( or spaces ) -- perhaps this what you mean by maxed out ?

    I have no idea what he means by max capacity unless he did a load test. Unless your house is extremely large and/or you have electric heat, I doubt you would ever come close to using a full 150 amps. As Canuk says the surge suppressor uses little power so should not add to load.

    Dmurr, you can buy surge protectors that: mount inside the service entrance panel on a stab, lay inside with wires run to an existing two pole breaker & the neutral, outside the panel through a knock-out (run wires to a 2 pole breaker and the neutral bus, per directions.

    Keep the wires as short and straight as possible (3" to 4" is good), or the lightning will jump off the wire and you will loose your protection.

    It's a good investment that can save a bundle. You may never know what didn't burn your house down, unless the protector melts during a storm.

    Guys,

    Thanks a lot for the advice. I really appreciate it. I have a 2,000 sq. foot house that runs on oil heat (punishment for living in Rhode Island), so I'm definitely not using a ton of electricity.

    And I'm not sure what my electrician meant either, but I thought I'd pass it along.

    Thanks again!

    Dave

    Do these "whole House" surge protectors prevent damage from surges within the house (like from a loose neutral in a j-box) or just on the incoming service? Both?
