A customer requires power monitoring at the secondary of the following transformer:
KVA: 1000
Primary Volts: 13200 VAC
Primary Current: 43.7
Secondary Volts: 480Y/277
Secondary Amps: 1203
Proposed installation has the monitoring device mounted on a wall @ 8' away, total lead length @ 12', CT leads and voltage leads in separate conduits. Monitoring equipment voltage leads terminate at a disconnect/fuse holder with FNQ-R-5 fuses. SCCR rating is "Exempt Per UL-508A Paragraph 49.5".
I've read 240.21(C) and don't see how this could be compliant. Most of the monitoring equipment I'm familiar with is entirely enclosed in switchgear as mentioned in the article.
If I'm referencing the wrong article, please direct me where to find the correct reference to determine placement of OC/Short Circuit protection and conductor size, if it's even possible.
