Re: Surge Protection Devices - Single Phase and Single Pole - WHY ?
I suggest that if a SPD is located close to a neutral-ground connection, it doesn't help to protect neutral. In all other cases, +N will potentially add some protection.2 · -
Re: Surge Protection Devices - Single Phase and Single Pole - WHY ?
Mike, you have it reversed. A surge from upstream (as in a strike to wires between the transformer and house, NOT a direct strike on equipment in the house) WON'T come in on neutral (at the panel) ke…1 · -
Re: Surge Protection Devices - Single Phase and Single Pole - WHY ?
Say the concern is only a lightning surge coming in from somewhere upstream and getting to some in-house device. Such a surge can only come in on the hot wire (neutral is grounded at box and the tran…2 · -
Re: Concerned about my 3 year old AGM marine batteries
Logically, as batteries age and get some permanent sulfation, you aren't going to get the same peak voltage (because the acid is weaker). Trying to push it higher will only cause more wear. There sho…1 · -
Re: Surge Protection Devices - Single Phase and Single Pole - WHY ?
> green wire ground and neutral are always at the same potential. They are close to the same potential until you have a lighting strike in the wrong place (eg, on the neutral line). Then they can …2 ·
