UNASSEMBLED PANELBOARDS
The Siemens Advantage
Revised P1 with 3VA options usa.siemens.com/powerdistribution

New Revised P1 Unassembled Panelboards
To better serve the needs of our customers, we are proud to announce that we are an Authorized Siemens Unassembled Panelboard Distributor. What this means to you is product flexibility, quicker job turn-around, and affordable pricing. All Siemens unassembled panelboards are fully backed for high-quality, trouble-free operation and are labeled as Suitable for use as Service Entrance Equipment.
Same day availability: Over the counter availability means you're on and off the job without the delays that come with waiting for factory assembled panelboards.
Product consistency: Whether you are starting a new project, replacing parts, or adding on to an existing project, the unassembled panelboard offering is an exact match to the Siemens factory built panelboards (feed-thru versions only). While this ensures that you enjoy the same great features of the P1 panelboard, it also guarantees your job sites will have the same look, quality, and parts whether you ordered them factory-built, utilized our unassembled panelboard inventory, or used a combination of the two. (Note: Non-feed-thru variations are available as factory assembled without subfeed space in a 6" shorter enclosure.)
Flexibility and ease of assembly: Customer oriented design creates installation convenience. For all of its one-of-akind features, the P1 panelboard is also designed to be extremely user-friendly. For instance, field convertible main breaker and main lug kits, (through 400 amps), will allow you to switch from main lug to main breaker, and vice versa with no change in box size or additional cabling. Plus, lay-in construction and/or removable lugs make wiring the main and neutral lugs easier and faster. To further speed wiring, as well as reduce clutter, the P1 panel also features a split neutral design and branch neutral connections are near the breaker connections. Additionally, field addable sub-fed breakers (up to 250 amps) or feed through lug kits can be field installed without utilizing any of your feeder breaker positions or increasing your box height. Furthermore, the unique design allows the panel to be inverted in the field and keep its labeling legible.
New for Revised P1 Panelboards 1) BL/BQD and xGB/3VA41 type breakers are now available in main and subfeed
positions (using the same universal strap kit). 2) 3VA 250A and 400A Main Breakers are available in both TMTU (Thermal
magnetic trip) and ETU (Electronic Trip) variations. 250A are also available for Sub-feed. 3) 2/0 Neutral strips are now standard on all P18... series interiors for xGB/3VA41 breakers. Accessory kits are also available for field replacement. 4) BT twin 15A and 20A breakers are now available that can be placed wherever a 1-pole BL 15A or 20A can be used.

Revised P1 Unassembled Panelboards (introduced 2015) offer a wealth of features and benefits!

1 Completely symmetrical boxes may be

s

mounted with either end up. There are two

(or four) pre-punched equipment ground

connector locations for contractor friendly

installation.

a

2 Box comes pre-punched for optional, field-

installable door-in-door or hinge-to-box style

trims. The panel box will accept both

standard ground connector (EGK and ECGK)

assemblies and insulated ground connector

kits (IGK and ICGK).

3 Interior is completely symmetrical allowing it
to be changed from top to bottom feed by simply rotating the interior.

4 Choose either a Main Breaker kit or Main Lug

kit with which to terminate your incoming

cables. Main lug kits are contractor friendly

with lay in lugs (or removable lugs) through

d

f

350 Kcmil (250 amp panel) or (1) 600 Kcmil or (2) 250 Kcmil connectors for 400 amp

panels. No line connectors in the P1 panel

g

require multiple wires under one screw. Main

Breaker kits (250 amps and below) are

horizontally mounted allowing field

convertible top or bottom feeds to be

performed easily. MLO kits and Main Breaker

Kits are interchangeable and can be changed/

added in the field without making changes to

the enclosure or interior.

5 Branch neutral connections are near the

breaker connections to speed wiring and

reduce clutter. The standard P1 neutral is

h

rated for 100% of the panel's ampacity and

will accept copper or aluminum wire.

Optional 200% neutral kits and 2/0 neutral

kits are also available. (2/0 neutrals are now

standard on all P18... series interiors)

6 The panel includes space to add (1) sub-feed

breaker (max 250 amps), feed-thru lugs or

j

TPS3 or new TPS4 (SPD) kit. The P1 panel

with the TPS3/TPS4 SPD unit installed is

complementary listed to the standard for SPD

units and meets the requirements for an

electronic grade panelboard. (New BSPD

series Bolt-on Surge products can be added

in unit space freeing up this sub-feed space

for feed-thru lugs or sub-feed breaker)

k

7 Siemens standard trim has hidden hinges and

mounting hardware for added safety. The

rounded door corners not only enhance the

panel's appearance but also help to eliminate

injuries caused from sharp corners.

8 Semi-flush lock comes standard. Easily
identified locked position denoted by keyway
being horizontal when door has been locked.
