POWER CHECK

SAIL - - Gear -

Shore power con­nec­tions can be sketchy; some­times dock wiring isn’t all it should be, and re­verse polarity in par­tic­u­lar can be dan­ger­ous for your boat and for your crew. Usu­ally the first sign of this is when you’re al­ready hooked up to the dock pedestal and switch on your cir­cuit breaker at the on­board panel. A bet­ter way is to test the pedestal be­fore you plug your cord in; this handy twist-lock 30-amp tester from Hubbell could be a life­saver. Its LED read­outs will tell you what, if any­thing, is wrong with the power sup­ply and con­nec­tion. $89. Hubbell Ma­rine, Hubbell-ma­rine.com
