Please see attached riser diagram.
I've got a Natural Gas generator to be used for Emergency power that will supply a life safety branch.
We need to provide either a duel fuel generator (NG & LP) or a NG only with a UPS.
I have two questions:
1) Which is going to be the cheaper option? (Gnl contractor said a 850 gallon LP tank underground can cost up to $10K. A 500 gallon tank is only $2k. This is an issue I can resolve with the generator people as far as the right tank size.)
2) On the riser diagram, where is the best location to insert the UPS on the Em. branch? Right upstream of the ATS?
Thank You
