In Switchgear, there are two types of access Front & Rear Access, as further detailed below which define the Switchboard size
Front Access - All the cabling connections are accessible from the front and therefore the panel is typical wall mounted and only requires front access of a minimum of 1 Meter
Rear Access - Commonly known as Front & Rear Access, however, all the cables are accessible from the rear and therefore requires front and rear access of a minimum of 1 Meter
Typically fitted within a single section:
1No. ACB Incomer OR
18No. 250A MCCB's OR
8No. 630A MCCB OR
3No. 1600A MCCB
Populating additional sections is completed by adding the same size section next to the above and populating again with what units are required

FRONT ACCESS ONLY - CABLE CHAMBERS
For outgoing MCCB's the following cable chambers must be added to the LEFT & RIGHT-hand side of the section that has been populated. There are two types and are to be used as detailed below
FORM 4 TYPE 1-5 Panels use 500mm Wide Chamber
FORM 4 TYPE 6 Panels use 750mm Wide Chamber

Sizing Switchboards is not easy and not something to take for granted, it is arguably the number one requirement of all consultants while specifying switchgear. Due to the fast variance of switchgear, it is always advised that you seek ELECSPEC professional advice to ensure all design are accurate, this even more so when proceeding further past 3600A to 6300A device, this can be obtained by getting in touch just below on the bottom right
