i'm sitting at work
, watching a rare electrical
storm move through the bay area, and this prompted a thought - curious to see what you guys think.
is well grounded against lightning
strikes, but it occurs to me that:
(a) copper is a better conductor than aluminum
(b) the tricolor, strobe, anchor
light, anemometer and VHF antenna
are all at the top of the mast
and all have copper wiring
running down straight into my distribution panel, rendering the mast grounding less than fully effective at channeling 100% of the absorbed energy straight to ground. (and as an added bonus, routing all of that power exactly to where i don't want it)
has anyone considered the idea of having a harness at the base of the mast that could disconnect all of these wires, and perhaps recouple them directly to a keel
sure, the items you disconnected wouldn't work
, but if you were willing to forgo those systems, it seems like you'd have a greatly reduced risk of collateral electrical
damage should a strike occur. if you needed one or more, you could keep everything coupled per usual, and be in no worse shape than you would be otherwise.
i can't imagine i'm the first person to think of this, but i've never heard of it being done.
