Maximum Demand - Standby and Duty Motors
Maximum Demand - Standby and Duty Motors
(OP)
Hi Again All,
When doing maximum demand calcualations I assume one does not consider both the duty and standby motors where the duty/standby arrangement is provided. Both motors are the same size etc.
Functionally I am not sure how they operate and if they were to both run at the same time, i.e. when swapping from the standby pump to the duty pump, I would be in trouble as my TF would not handle the load
Any thoughts?

There is nothing in the local codes over here (Australia) that says your point of supply has to be able to sustain all the appliances on your network.

If you want to be a good engineer, you will have more success it you design a system that "works". Code are intended for safety and they do not care if a system works, but your client would who is paying the bills.
So the onus is on you to to design a sytstem that meets Owner's requirements. Codes are minimum statutary requirements that needs to be met and not a design criteria.
