I'm installing new wind
instruments , wind
and depth/speed combo. My old ones were separately wired,transducer to instrument to power each on their own circuit.
The new setup is daisy chained. The cable from the anenometer at the masthead comes down the mast
to a T connector inside the hull
. The depth/log transducer which is about a foot from the bottom of the mast
plugs into the T and then a third cable takes the data to the instruments in the cockpit
. Neat and easy and a doddle to install.
Then I thought, what if I get a lightning
strike? If the lightning
hits the masthead anenometer (highly likely) the current
will go straight down the cable directly via the Tconnect to the through hull
and sink the boat (!!!!)
Would it be better to put the Tconnect next to the instruments and run a cable back to the through hull or have I missed something?
