Hello,

I am designing power for an exterior heated enclosure for domestic water piping.

the pwr source will be from stand-by generator circuit.

does the heater have to be supervised?

if so, from where? Fire alarm and/or building management interface panel?

thanks in advance.

An overall picture of why you are heating the system would help any replies.

And welcome to ECN.

to keep the pipes from freezing. It is a aluminum enclsosure (HB8E-D) with dual 1900W heating elements. The circuit is fed from stand-by generator distribution.

not to be pointed in right direction for nfpa supervisory ckts.

thanks

Dbravo:

Welcome to ECN forums.

Additional information on the project is required;

Why are heaters required, other than freezing? What type/use group of structure/building?

Is the gen a legally required system, or is it an optional system?

Supervisory circuit to bldg mgt sounds like a good move. The FACP? Perhaps, if the water is destined for fire supression use.

More info will get you more answers and opinions.
