Panel Selection Factors
Basic information required when specifying panelboards is as follows:
• Environment
• Service (Voltage/Frequency/Phase)
• Interrupting capacity
• AMP Rating of Main (Lugs only or Breaker)
• Branch Breaker (Type/Number of Poles/Amperage)

Ordering Information
Specifying and ordering a complete panelboard assembly requires the
selection of three components.
(1) Basic Panel (2) Branch Breaker and (3) Options (if required). This method of cataloging permits a wide variety and maximizes circuit flexibility in our panelboard offering. Components supplied in each of these selections include:
1) Basic Panelboard Enclosures (page DE12)
• Explosion-proof enclosure consisting of box and cover
• Cover predrilled and plugged for maximum number of branch breaker
handles (handles not supplied) Box supplied with conduit openings
• Main circuit breaker and external handle (when specified)
• Panelboard internal chassis with buss bars but less branch circuit breakers
2) Branch Circuit Breakers (page DE15)

• Internal circuit breaker
• External handle mechanism with internal tripping mechanism
• Test pushbutton for GFI (when ordered)
• Lockout shield with on-off-trip-reset identification
3) Options - Accessories (page DE15)

Ordering Example
Specification is for a 3 phase 120/208 volt panel with 100 Amp main lugs
complete with (4) single pole 20 Amp (2) double pole 20 Amp and (1) three
pole 30 Amp branch breakers. Branch Breaker Total =

(4) 1 Pole = 4 Poles Total
(2) 2 Pole = 4 Poles Total

(1) 3 Pole = 3 Poles Total
Total 11 Branch Poles


Specification/Ordering Example
B7L20 - 312 - ML100 (Basic panelboard
enclosure) with:
(4) B7BLA1020 (1 Pole 20 Amp Branch)
(2) B7BLA2020 (2 Pole 20 Amp Branch)
(1) B7BLB3030 (3 Pole 30 Amp Branch)


Catalog Logic
See page DE16 for panelboard catalog
number logic for basic enclosures.

 

 

 

 

Cutler-Hammer type BA circuit breaker 1 - 2 or 3 pole.
Catalog numbers on this page are for the basic panelboard enclosure only
with a panel interior chassis containing main lugs or main breaker as illustrated. Internal branch breakers and external handles are NOT included in the basic enclosure catalog number and must be ordered as separate items.
Branch circuit loads The interior panel chassis supplied in B7L panel is limited to a maximum of 140 amperes at any one connection point. Breakers of 50 thru 100 amps must be installed opposite breakers of smaller amperage so as not to exceed the 140 ampere limitation.
