Control of 2-pole relay circuits in Echo Relay Panel Mains Feed

Question

I have 2-pole relays in my rack. Can I control the circuits they jointly serve individually? I.E. circuit 1 and 3 use a 2-pole breaker. Can I control 1 and 3 individually?

Explanation

If 2 circuits share a 2-pole relay, they will be controlled together. Splitting up a 2-pole circuit into two individually-controllable circuits requires single-pole breakers and relays, and should only be done by a qualified electrician.

CAUTION: Be aware the 2 pole relays/breakers are used for loads that require two phases of hot power, such as 208v or 240v circuits.  They are linked together for electrical safety purposes and should remain controlled together.  

 

Disconnecting a single hot of a two-pole circuit may cause damage to downstream equipment.

 

1 pole relays are to be used if the 2 circuits in question are 2 separate circuits wire to 2 separate loads.
