Single family dwelling during a remodel the plumber has replaced sections of hot and cold water lines with plastic water lines to connect to the faucets. There are only short sections of copper stubbed out at wall to connect faucets. According to 250.104(1) these isolated water lines need to be bonded using table 250.66. We have a 400 amp service fed with 600 mcm cu so a 1/0 cu bonding jumper would be required. This seems a little over sized just to bond a faucet. Am I interpreting this right? Looking for some thoughts on this.
