I am getting ready to pull an 220V/80A branch circuit to my new inside
heat pump. I am upgrading my 100A service to 200A locating the new
meter right next to the old one; and putting a new 200A load center,
then two branches; one to the existing 100A breaker box and another
branch circuit off the new 200A load center to the heat pump.

THE QUESTION IS:
I was advised to run a solid copper ground to my hot water heater, but
my water heater connects to everything with plastic pipe. I don't see
the point of running the wire to it.

I will be grounding the new meter; new load center, and existing load
centers to two existing ground electrodes right near the existing
meter. Since I already bought the 50' of #4 solid for the water heater
ground; I'll use that wire for this purpose
comments?



Hi Tim. I'm glad to hear that you've been continuing to do your


homework

with planning out this job and will soon be doing it. I'm thinking that


the

advice that you received about grounding the water heater was for the
installation of a bonding jumper. This is usually done at the water


heater

to bond the metal hot water, cold water, and gas pipes together. The


code

calls for all interior metal piping to be bonded together, but does not
specify that it must be at the water heater. If your water pipes are
non-metallic then there is no need for the bonding jumper.


What you just wrote reads like you're saying there is NO NEED to connect
a ground conductor to an electric water heater.

Do you really mean that John?

Jeff, the original poster's second post clarified that there already is an
equipment ground to the electric water heater.


Agreed, but his clarification was made about an hour after I'd posted my
reply. (If I believe the times of day on newsgroup posts, which I freely
confess sometimes confuse me.)

I said it appears that he
does not need the bonding jumper between pipes which I am presuming someone
told him to do. These are two different things that do-it-yourselfers can
get confused about.

Lighten up on the guy. He has posted here several times already seeking
quality information before he starts the job. Too often I have seen people
post questions after they have started the project without knowing all that
they need to know.


Agreed, I posted while I was waiting for my morning coffee to brew, and
I really shouldn't communicate with any other living thing, including
our cat Lard Ass, until I've had my first cup of java of the day.

Peace,

Jeff
