Tankless Water Heater Panel Connection
I'm installing a tankless water heater that requires one 60 amp breaker and #6 wire to serve it. I have installed breakers and new circuits in panels before but this panel is inset into the wall of the garage which presents an issue. Here's some info and my plan:
- Run individual #6 conductors (& ground) in PVC conduit from the heater to the panel along the surface of the garage wall (about 12 feet).
- The water heater has a 3-foot pigtail coming out of it with 2 #6 wires and one #8 ground.
- I plan to have a junction box to connect my new #6 wires to this pigtail, then run the new wires in conduit the 12 feet over to the panel.
- (for code purposes, I'm in Jacksonville, FL)
- (panel is a Siemens with 150 amp service)
- (I'm removing the old 30 amp breaker that served the old tank-style water heater)
- (a local electrician told me that my panel could definitely handle the new 60 amp breaker provided I took the old 30 out of service)
My question is, well.. first, does this sound ok so far, and then how do I route the three individual #6 wires the last 5 or 6 inches from the surface conduit run into the wall (through the drywall) so I can enter the panel though a knockout? I'm not sure there's enough room for a 90 degree sweep elbow to make that turn. Or can I just use a small 90 inside the wall from a junction box next to the panel (the box would provide a point for the surface conduit run to terminate).
Thanks.

You plan sounds fine. The only change you need to make is if the tankless is direct wired you need to have a disconnect instead of a junction box. An easy/cheap disconnect would be a 60 amp A/C non-fused disconnect. They run about $8.

I was under the impression the water heater was in another room.

It is is the same room within sight of the panel (no conduit through doorways - haha). My main concern was how to make the connection to the panel from where I punch through the drywall at the end of the conduit (j-box). I didn't want to just have my 3 individual wires in the wall even for just 5 or 6 inches. So, I will run the conduit from the water heater over to just beside the panel, put in a junction box, then do 1 of 2 things:
1. Wire nut the #6 wires to 6/2 Romex and run it into the panel behind the drywall.
2. Use a short 90 degree elbow connecting the back of the j-box to the panel knockout for that last 6 inches behind the drywall.

Option #1 is how I would likely do it.

I would agree,remove some of the drywall and bring the pipe directly into the panel,no need to make any more splices.
