19-267 Log #4776 NEC-P19 Final Action: Accept in Principle
(555.13(B)(4)(b))
_______________________________________________________________
Submitter: Julian R. Burns, Quality Power Solutions, Inc.
Recommendation: Add: Exception No. 1 Where listed portable power cables are installed in accordance to the requirements as permitted by 551.13(4)(a) and terminate in a listed marina pedestal/power center employing terminal blocks/bars, the installation of a junction shall not be required.
Substantiation: New listed and advanced marina power pedestals and power centers are available and in today’s applications, boats are the size of mobile homes requiring, in some cases, two 100 Amp feeders. By installing an additional junction box, when the flexible cables can in many cases run continuous from the supply to the power pedestal just provides an additional point for corrosion and burnt up connections. The power pedestals already have the terminal blocks.
Note: Supporting material is available for review at NFPA Headquarters.
