The city electric plan checker needs the following on the plans:
: DOCUMENTATION REGARDING SERIES BREAKERS :
Can you guys tell me what he means?
What the Plans Examiner is requesting here is for Manufacturer's Spec documents, to be submitted to the Plan Check firm (in hard copy, or "printed" format), which are relavent to a Series Rated System.
These documents will list devices and equipment, that are acceptable to be installed within a Series Rated System. Manufacturer's part numbers + categories will be referenced, as to their use downstream of a given Service Section or Gear Section & OCPD.
If your System IS NOT
Series Rated, then write in your reply to the Correction notice:"This Electrical System Is Fully Rated, Not Series Rated"
, then submit the marked up correction list to the P/C firm (P/C = Plan Check).
Submit it, along with your contact information + note to have the P/C person contact you for further questions.
If the System is / will be Series Rated, then go to the Manufacturer's website, and printout / download "Cut-Sheets" for their approved combinations of equipment and devices usable on Series Rated Systems.
If you are unsure if the System is / is not Series Rated:
- Review the 1 Line Diagram + spec notes of the Planset, look for some indication of Series Rating,
- Verify the On-Site conditions - need to know the Fault Levels at Panelboards, Disconnects, Gear Sections and the Service Equipment.
Maybe there is a high fault level indicated at a remote Panelboard ( > 10KAIC ), which drew attention to the P/C during the exam - and this is why they request the documents.
If this project is Design / Build, and you are the designer, you _should_ know if the System is / will be Series Rated.
I include notes on the cover page, the 1 Line page, and the Panel Schedule page(s) which call out if a System is or is not Series Rated - as follows:
* This System Is a _FULLY RATED_ System (NOT Series Rated).
SCA levels at various points along the system do not exceed the AIR (AIC) of installed Overcurrent Devices or Panels.
* This System Is _SERIES RATED_.
Supporting documents are attached to this Planset, and will be submitted as separate documents - in addition to this Planset - for Plan Examination.
Overcurrent Devices, Panelboards, Service Equipment and other related Equipment intended for use in a Series Rated fashion, have been listed in the Materials Specifications list of this Planset, and have been identified at points on the 1 Line Diagram(s).
