Poles/ Amperage)
Ordering Information
Specifying and ordering a complete
Panelboard explosion proof or circuit breaker explosion proof 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)
• Panel explosion proof or circuit breaker explosion proof 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)
• Panel explosion proof or circuit breaker explosion proof 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
