P1 Panelboards • Quick reference for selection and application

1. Non-Feed-thru (NFT) variations of the P1 Panels are now

available for Factory assembled only (not UPB):

• Feed-Thru (FT) versions are versions with a Sub-feed space

that can be occupied by Feed-thru lugs, Subfeed Breaker or

an SPD device. All Original P1 devices were FT versions.

• Non-Feed-thru (NFT) versions do not have the Subfeed

space and therefore can fit into an enclosure 6“ smaller

than the FT version.

The NFT version will have a List price lower than the FT

version if configured the same.

• Both FT and NFT variations are fully invertible in the field and

can be used for either Top-feed or Bottom-feed applications.

2. Extended Circuits are now available:

Currently only 18, 30 and 42 circuits are available  54

and 66 “extended circuit” panels are added for Revised P1

a) P1-250A will have FT and NFT variations for all circuits:

18, 30, 42, 54 and 66 (xGB panels only available as FT)

b) P1-400A will have FT and NFT variations for 30, 42, 54

circuits only. (xGB panels only available as FT)

• The 66 circuit variation of 400A is only available in NFT

due to enclosure size limit of 74“ high.

• Also P1-400A will not be available in 18 circuit variations.

 Benefits: Many P2 and P3 applications can now move down to

the P1 platform!

3. New Neutral Configurations are now available:

• The new Neutral system has been developed to

accommodate the extended circuit variations without

increasing costs.

• The new configuration is still a split neutral arrangement

with connections down either side of the interior, but it is

not full length as before. Neutral connections are still near

the breakers, but not adjacent to each breaker connection.

Many configurations have extra connections and some larger

configurations will allow adding more connections if needed.

4 Unassembled Panelboard Program Changes:

• The UPB program will only get 54 circuit added to the

program for both P1-250A and P1-400A.

• All UPB interiors will be the FT variation, the same as Original

P1. (400A - 18 circuit is no longer available)

• All old Accessories/Kits will remain available for future needs

in Original P1 installations.

• New Accessories/Kits are available - most are same as old kits

with “A” added to end of part number. (see below)

5. Accessories and Kits for Revised P1 are replacing most of

the Original P1 Kits:

(most simply add an “A” to end of old kit number)

a) All Main/Subfeed Breaker Mounting kits are new. Both “Strap

Kits” and Kits with Breakers.

b) All Main Lug Kits are new.

c) All Neutral Lug Kits are new.

Revised P1 Panelboard FAQ’s

New Features and Options for “Revised P1” Offering compared to the “Original P1” panels

6. BL/BQD and xGB (NGB/HGB/LGB) Main Breaker Usage is now

only available as a Back-Fed variation.

• The Revised P1 interior does not have “strap kits” for the BL/

BQD and xGB series of breakers to be used in the “Main” or

“Sub-Feed” positions. If needed to be used as a Main - we

now have a “Main Label Kit” that allows the placement of the

breaker in unit space to be used as the Main when labeled

properly. This does reduce unit space by “2 circuits” in a single

phase panel and by “3 circuits” in a 3-phase panel. Since 54 and

66 circuit panels are now available - this should not be an issue.

7. New B-Phase Bus configuration eliminates “Hump-bus” design

• The new flat bus with “B-Phase” connector has many

benefits. Increases productivity at the plant and allows

for replacement connectors in the field in case of a

“stripped” connection.

• Accessory kits for both CU and AL variations of the B-Phase

Connectors and A/C Connectors will be available for repair

purposes only.

8. xGB Breaker series expansion: NGB remains, but HGB and LGB

have been added

• This addition to the Breaker line will now allow many

configurations to use the Revised P1 series or the P2 series

platforms instead of the P3 platform. Net pricing to customer

will be lower. See new ratings below:

NGB – 25,000 A IR Max. @ 480/277V AC / 100,000 A IR @ 240V AC

HGB – 35,000 A IR Max. @ 480/277V AC / 100,000 A IR @ 240V AC

LGB – 65,000 A IR Max. @ 480/277V AC / 100,000 A IR @ 240V AC

9. Misc. additional features:

a) New 750 kcmil AL/CU MLO will be available as an option for

400A. (CU cable limited to 600kcmil)

b) New 2/0 neutral kits are available. (used with 125A xGB

and others) (Only available as a field installable option)

c) New filler DFFP1 is introduced replacing QF3 (fits tighter

in deadfront)

10. Misc. additional changes/notes:

a) All DC voltage offerings are removed from scope of Revised

P1 devices.

 Customers will be moved to a P2 configuration for

these DC Voltage applications.

b) Limits on branch breaker size for 250A 18 circuit only:

• The new Revised P1 (18 circuit 250A only) is limited to 100A per

connection (200A per pair)

• Original P1 and the Revised P1 allows for the following:

(except as noted above)

1) 100A per connection (200A per pair) for BL/BQD construction

2) 125A per connection (250A per pair) for xGB construction

 Some of our competition limits the total to 140A per pair on

some panels.
