Interactive animation on the subject
The animation is based on 2 Control Panels (control cabinets), one built conforming to the IEC standard and
the other conforming to the UL standard. The user will be able to navigate through the animation interactively,
thus gaining a better understanding of UL specifics in the context of Industrial Control Panels.
PROCEDURE:
Click one of the devices installed in the Panels (either the IEC or the UL Panel) to display both information
about that device and the corresponding device in the other Panel.
Click the device again to display both detailed information (technical data, for example) and the UL specifics.
Use the
buttons to scroll through the animation. The

SCCR
Requirement from NEC 2011 Art. 409.110 and UL 508A, Art. 52:
 Among the requirements to be met is that the SCCR
(short-circuit current rating) of the entire Control Panel must be marked on each Industrial Control Panel.
 The SCCR value shall ensure that the Panel is only connected to systems where the prospective short-circuit
current will be less than or equal to the value on the rating plate.
Based on NEC 2011 Art. 409.110, there are essentially 3 different ways in which the SCCR value of a Panel can be
determined:
Option 1:
Option 2:
Option 3:
The SCCR value of each individual Panel or
Panel unit is officially listed by a laboratory in
the presence of UL test engineers from UL.
Using pre-tested versions or buying such pretested Standard Industrial Control Panels.
Complete analysis of the Industrial Control
Panel in accordance with UL 508A SB4.
 This method is the one used most often.
 It is described below.

Industry Sector
SCCR
Determination of the short-circuit current (SCCR) in accordance with NEC 409.110 (4)
Step 1 (mandatory):
 Listing of the SCCR values of the devices (values on the device or in the UL report)
 The smallest value determines the total short-circuit rating of the Panel!
Step 2 (mandatory):
 Listing of the SCCR values of the devices from UL 508A Table SB 4.1 (if an SCCR value has not been specified)
Step 3 (optional):
 Listing of the SCCR values of switchgear assemblies
 Series Rating Tests (series connection of at least 2 devices which can respond to a short circuit instantaneously)
 Combination tests (series connection of devices of any type)

Commissioning/Acceptance
Every electrical machine or system in the USA is checked by an inspector known as the AHJ (Authority
Having Jurisdiction) before it can be commissioned.
Acceptance is based on the NEC (National Electrical Code, also known as NFPA 70), the relevant
application-specific guidelines such as NFPA 79, as well as any local standards or specifications.
 In the USA, acceptance is a legal requirement.
The next graphic (see next slide) outlines four possible ways of arranging acceptance.
