I always find it interesting that the power chain is measured and monitored in multiple locations throughout most data centers but is often forgotten once the power enters the data center cabinet. Especially considering that roughly half of the power used (or more) can be traced directly to the cabinet ...

Ask the Engineer- Will Branch Circuit Protection Eliminate Concern for Tripping an Upstream Breaker?
Posted by Annie Paquette on November 29, 2010
The combined load of branches on a power strip may be capable of exceeding the upstream input protection. There is a fundamental misunderstanding of the purpose of the power strip internal fuse protection. The fuses are not there to keep the upstream breaker from tripping. Circuit protection within the power ...

A Few Words About Replacing Fuses and Resetting Circuit Breakers
Posted by Annie Paquette on April 08, 2013
As a Systems Engineer who spends a fair amount of time responding to inquiries received through our Technical Support department I often hear "The PDU blew a fuse. I replaced it but it blew again. Something is wrong with the PDU. Please send me a new one." Would that we could, but the PDU is doing what it should. In this blog, Servertech will talk about why fuses blow and circuit breakers trip, and how to respond to re-energize the outlet branch safely and effectively.

Ask The Engineer- Should Neutral Conductors Be Oversized?
Posted by Annie Paquette on December 16, 2009
The question at large- "I am presently evaluating a CDU model #CS-27VY-L30M and have noticed that the power input cordage does not involve an oversized neutral conductor. All five conductors are 10-gauge AWG. Isn't an oversized neutral required to avoid the possibility of overheating the conductor?"
