Circuit Breaker Enclosures
Wiring diagram location and information
Specifications and Date Code for product
NOTE: This information will generally apply to ALL the Molded Case Circuit Breaker Enclosures(The F-frame, B-Frame, H-frame, the J-frame, the L-frame, the M-frame and P-Frame). But for the video a J250S was used.
The wiring diagram on the circuit breaker enclosures will be located on, one of the inside sidewalls of the enclosure. All the necessary information for the enclosure will be on the wiring diagram and will contain the following;
1) Catalog and series number of the enclosure
2) What type of Circuit breakers that can be used
3) Any accessory that can be used in the enclosure, like the solid neutral and equipment ground kit
4) The UL listed catalog number Prefixes for the breakers that can be used in the enclosure
5) Maximum wire sizes for the enclosure(NOTE: Sometimes the breaker can accept larger wire, BUT the enclosure wire bending space will be limited to what the wiring diagram shows)
6) The Wiring schematics
7) The Short Circuit Current Rating information for each breaker at each voltage level
8) The Date code. The date code will be an ink stamp, generally located on the inside back wall of the enclosure. The Date Code will be a 5 or 6 digit code and will read as follows; first two digits = year, the 2nd two digits = week of the year, the 5th digit = the day of the week and the last digit(if used) = the shift. For example, 183241 is year - 2018, week of year -32, day of week - 4 and shift - 1. (Aug. 9th, 2018)
Yes, all of the miniature circuit breakers have a "trip free" mechanism which enables them to trip under fault conditions even if the handle is locked ON or held ON manually.
The replacement sliding type door catch suitable for the Isobar MGAN and MGBN range of Isobar distribution boards, enclosures and extension boxes is part number: MGSDC
NOTE : this can also be used on the new range of Acti9 Distribution Boards
Acti 9 Isobar P - A Type & Acti 9 Isobar P - B Type
No, the Isobar and Acti 9 range of distribution boards are designed for the C60H and iC60H range of circuit breakers as outgoers.
The C120 circuit breakers do not fit because they are 27mm wide per pole, where as the C60H range are 18mm wide per pole.
It is possible to feed/cable off the pan via the SEA9TB1001 ( 1 per phase) and cable into a din extension enclosure with the C120 or iC120 breakers in but only to a maximum Amperage of 100A.
Incomers up to and including 125A
The Isolators and RCD's fit directly into the distribution boards.
Incomers above 125A
Isolators and MCCB's fit directly into the distribution boards but come complete with an extension box to allow for cabling space.
The 160A RCD incomer is a larger device, and fits into both the distribution board and the extension box included in the kit. Space is still available for incoming cables.
The extension boxes included with incomers above 125A are 270mm high.
Incomers above 125A are also available without the extension boxes. Cabling space will have to be provided by other means.
