do it as well as you can,but learn to do it better
my bulk tank set up had a wander lead in soft 8mm cable with a crock clip secured to the base frame, which in turn had a 3 ft earth spike driven itno the ground, plus it was also connected back into my 3ph supply's system too .. just clip onto a decent earth point on the vehicle when dispensingWhat’s best way to ground them?
you could make up a lead with a 3 pin one end using just the earth pin and crock clip on t'other (assuming your leccy system has a good earth point)
forecourt systems have none of this and rely on the dispensing nozzle/gun to make a decent ground connection
you'd have to be pretty unlucky to generate a static spark, but earthing the dispensing/receiving bottles would negate that risk (earth one and jump lead between them)
