Hi James, A quick Google tells me APC ATS are break before make, so that is certainly not the defining feature of an ATS vs. STS. For cost effective provision of a 'C feed' in racks to catch those pesky single corded devices you just can't live without I see no reason at all to go to the expense

Chad, That's all well and good but when you're paying a premium price for services of this fashion you expect a certain level of service. There is a risk no matter what when switching from power supplies taking extra load they would not usually take as well as swing load issues with PDU's. I

If you have single fed equipment in your rack that needs planning before it can be shut down, do you not run a totally forseeable and preventable risk then should that one feed trip? This is what ATS are for. Sam On Thursday, 10 August 2017, Shaun McGuane wrote: > HI Simon, > > > > Thank you
