Electric Water Heater Wiring

My condo in Calif. is over 30 years old. The EWH is in the garage. I need 220vac for a table saw, 8.3A, and was looking to get it from the WH circuit, 30A. (Running a new 220 circuit to the garage next to the EWH circuit is next to impossible.)

Looking at the present configuration, 10/2 w/gnd, goes from the WH in flex conduit three feet into the dry wall where the conduit abruptly stops. No junction box. The romex continues as a home run to the breaker panel several rooms and 40 feet away. It doesn't look "to code" with the flex stopping just out of sight in the wall. Is this to code?

Second, does the EWH need to be on a home run to the panel or can I put in a junction box where the flex enters the wall and wire an outlet for the saw? Presently there is no disconnect for the EWH. Does there need to be one?

Thanks in advance for your response.

The water heater is supplied by a 30A breaker. For your table saw, you would need to install a 15A or, perhaps, a 20A 220 receptical. Neither are allowed to be on a 30A circuit.

Chirkware: I was afraid of that!

Thanks, Cliff
