Hi All. How do you typically size circuit breaker size for instantaneous water heaters? for 240V and 208V. I'm looking at the HA036240. As you can see in the attached It shows (4x38) for 240V and (4x32) for 208. My system is 208V, taking into consideration 32 X 125% = i end up with a 40A Breaker for each circuit. Now from what i see regarding these water heaters (different manufacturers) Is typically they show 240V and a recommended 40A breakers for a 36KW, they never show 208V in many instances. This particular one shows amperage: So 40A breaker for 208 or should it be 35A for 208?
Thank you,
Thank you,
