My client wants a back-up generator for his 125HP, 480V, 3phase fire pump motor. The fire pump controller is an 'across-the-line' starter type.
I have gone through some sizing software provided by generator manufacturers and I came up with a 200kW unit. The factory guy tells me I need a 500kW...
I've got a client who is getting a new 750KVA transformer from his utility. The new transformer is delta on the primary and wye on the secondary. His existing transformer is a 500KVA bank that is delta on both the primary and secondary.
What effects, if any, will this service change have upon...
The conduit that supplies my client's fire pump controller with power runs through a room not protected by sprinklers. Is there a product that I can apply (foam, blanket, etc.) to this conduit to make it fire resistant, even fire proof. Re-routing the conduit is not an option.
Thanks...
