ABB RNSB12B8445A – Frequently Asked Questions

1) Does the ABB RNSB12B8445A panelboard come with breakers installed?
No breakers are included. The RNSB12B8445A ships as an enclosure and interior with 32 empty breaker spaces, so the contractor specifies and installs the breaker types, pole counts, and ampacities the job calls for. Budget the breakers as a separate line item, and expect to build out circuits incrementally if the load is being added over time.
2) Can an ABB 1200A NEMA 1 panelboard be installed outdoors or in a wash-down area?
No. NEMA 1 is a general-purpose indoor rating, intended for dry, non-hazardous locations like an electrical room or distribution equipment room. It offers no protection against rain, wind-driven dust, or hosedown, so an exterior wall, a parking structure, or a wet process area needs a NEMA 3R or NEMA 4X enclosure instead.
3) How much wall space do I need for the ABB 1200A panelboard enclosure?
The enclosure footprint is 84 by 45 inches, so plan on a full-height section of wall roughly seven feet tall. That is before working clearance in front of the equipment, which for a 1200A panelboard is governed by the electrical code for the system voltage and has to be kept clear of storage, piping, and door swing.
4) Is 32 breaker spaces enough for a 1200A distribution panel?
Thirty-two spaces is a distribution-panel count, not a lighting-and-appliance count. At 1200A you are typically feeding large branch or feeder breakers to subpanels, motor control centers, and mechanical equipment, so the spaces get consumed by multi-pole devices rather than single-pole circuits. Count your poles, not your circuits: a bank of three-pole feeders eats through 32 spaces fast. If you need dozens of small branch circuits, feed downstream lighting panels from this board instead of trying to land them here.
5) What is the ABB part number for the 1200A 84 x 45 panelboard?
Order it as ABB RNSB12B8445A. That is the single model covering the 1200A NEMA 1 enclosure with 32 breaker spaces in the 84 by 45 inch size, so there is no finish, voltage, or size option to select on the order.
6) Can I use this ABB panelboard to replace an existing panel in an electrical room retrofit?
It is built for exactly that kind of work, alongside new construction and switchgear lineups. The practical checks on a retrofit are physical and electrical, not brand: the 84 by 45 inch enclosure has to fit the existing wall space and clearances, the service has to suit a 1200A board, and because no breakers ship with it, the breaker family you install has to match what the interior accepts. Confirm the incoming feeder and grounding arrangement before you cut anything loose.
7) Is this a main breaker panel or a main lug panelboard?
The RNSB12B8445A is rated for 1200A main service and ships with all 32 spaces empty, so whatever main device the design calls for is part of the breaker selection rather than something preinstalled. Have your engineer confirm the main arrangement on the one-line drawing before ordering breakers, since that decision drives which spaces are consumed at the top of the board.
8) How many ABB 1200A panelboard enclosures come in one order?
One each. The RNSB12B8445A is packaged and shipped as a single unit, which matters for receiving on a 1200A enclosure this size, it is a rigging and freight item rather than something that comes off a parcel truck in cartons.
