In a nutshell the answer is, Yes. The why takes a bit longer to explain. The most basic explanation on why wire size (thickness) matters is because the thinner a wire is (higher gauge) the more resistance there will be to the flow of current. More resistance means more energy loss, more energy loss means higher electricity cost, more resistance means more heat, more heat increases the chances of wire failure and combustion. A practical example: Straton Electrical was recently asked … [Read more...] about Does Size Really Matter For My Electrical Cable?
