Branch Circuit Requirements - HP StorageWorks XP128 Installation Manual

Branch circuit requirements

Note
Preparing for installation
To protect your disk array, your building must be wired correctly. Each
supply ("hot") conductor must be protected by a short-circuit protective
device and by an overcurrent protective device. The current specifications
for the overcurrent protective devices required for single-phase operation
are listed in the table on
The protective device must comply with national standards of the country
where the units is to be installed (USA). If a protective device interrupts a
supply conductor, it must also interrupt all other supply conductors.
In many cases, local codes do not allow a branch circuit fitted with a
50-amp receptacle or connector to be protected by an overcurrent
protection device with a rating lower than 50 amps. You can order your HP
Disk Array XP128 with the 30-amp power option to comply with these
local codes. Your electrician knows the appropriate code requirements for
your location/site.
