ENCLOSURES AND
JUNCTION BOXES

confine an explosive force within the
enclosure, they are strong enough to
withstand the effects of corrosion and time.

Defining maximum terminal block quantity according to power dissipation:
•	 Junction boxes used for instrumentation applications carry very low current levels. Therefore there is no risk of overheating whatever the
number of terminals inside the box.
•	 For applications other than instrumentation, the following tables allow you to define your junction box depending on the number of terminals
and the maximum authorized current being carried.

3. Defining maximum terminal block quantity according to power dissipation:
•	 Junction boxes used for instrumentation applications have very low current levels, therefore there is no risk of overheating whatever the
number of terminals inside the box.
•	 For applications other than instrumentation, the following tables allow you to define your junction box depending on the number of terminals
and the maximum authorized current being carried with feed-through terminals.
•	 For single feed terminals using cross connection, please consult your local representative for a calculation.
For other terminal block configurations, please consult our drilling guide available online at: www.appletonelec.com.

3. Defining maximum terminal block quantity according to power dissipation:
•	 Junction boxes used for instrumentation applications have very low current levels, therefore there is no risk of overheating whatever the
number of terminals inside the box.
•	 For applications other than instrumentation, the following tables allow you to define your junction box depending on the number of terminals
and the maximum authorized current being carried with feed-through terminals.
•	 For single feed terminals using cross connection, please consult your local representative for a calculation.
For other terminal block configurations, please consult our drilling guide available online at: www.appletonelec.com

3. Defining maximum terminal block quantity according to power dissipation:
•	 Junction boxes used for instrumentation applications carry very low current levels. Therefore there is no risk of overheating whatever the
number of terminals inside the box.
•	 For applications other than instrumentation, the following tables allow you to define your junction box depending on the number of terminals
and the maximum authorized current being carried with feed-through terminals.
•	 For single feed terminals using cross connection, consult factory for calculation.
For other terminal block configurations, please consult our drilling guide available online at www.egsatx.com.

If a “Standard Conduit Opening Arrangement” is not suitable for the
application, or when openings are to be more accurately spaced,
submit sketch, locating openings (1) from centerlines of box and
(2) from outside back of box (or from mounting lug surface if lugs
are supplied).

Determine catalog number as follows: (1) select GUBB junction
box catalog number; (2) select “Conduit Opening Arrangement
Diagram” number; and (3) select symbols that represent conduit
opening sizes from “Symbol Table.”
Where no opening is required, the symbol 0 must be inserted.
Add suffix for other Optional Features. The various divisions of the
complete catalog number should be separated by dashes.
Example
The junction box selected is GUBB-33 and the “Conduit Opening
Arrangement” is diagram #1. Opening “a” is to be 3/4”; “b”, no
opening required; “c”, 2”; and “d”, 1-1/4”.

If a “Standard Conduit Opening Arrangement” is not suitable for the
application, or when openings are to be more accurately spaced,
submit sketch, locating openings (1) from centerlines of box and
(2) from outside back of box (or from mounting lug surface if lugs
are supplied).

Determine catalog number as follows: (1) select AGUB enclosure
catalog number; (2) select “Conduit Opening Arrangement
Diagram” number; and (3) select symbols that represent conduit
opening sizes from “Symbol Table.”
Where no opening is required, the symbol 0 must be inserted.
Add suffix for other Optional Features. The various divisions of the
complete catalog number should be separated by dashes.
Example
The junction box selected is AGUB443A and the “Conduit Opening
Arrangement” is diagram #1. Opening “a” is to be 3/4”; “b”, no
opening required; “c”, 2”; and “d”, 1-1/4”.
In this example, the complete catalog number is
AGUB443A-1-BOFD
Standard Conduit Opening Arrangement Diagrams
Opening “a” is always TOP of box

Symbol Table

Opening “a” is always TOP of box. All conduit openings will be located in
centerline of walls and evenly spaced unless otherwise specified.

Determine catalog number as follows:
(1) Select EXB junction box catalog number
(2) Select “Conduit Opening Arrangement Diagram” number
(3) Select symbols that represent conduit opening sizes from
“Symbol Table.”
Where no opening is required, the symbol 0 must be inserted.
Add suffix for other optional features. The various divisions of the
complete catalog number should be separated by dashes.
Example:
The junction box selected is EXB181208 with steel mounting plate
and the “Conduit Opening Arrangement” is diagram #1. Opening
“a” is to be 1/2”; “b”, 1-1/4”; “c”, no opening needed; and “d”,
1-1/2”. In this example, the complete catalog number is:

† Type DTX boxes must have a minimum of 3-1/2 full threads at all conduit entrances. The “Max. Conduit Size” listed herein indicates the maximum drilled and
tapped conduit entrance which can be machined into the four unbossed sides of a given box to provide these 3-1/2 full threads. If larger conduit openings
than those listed herein are required, bosses can be supplied by us at an additional cost to provide the minimum 3-1/2 full thread requirement. In addition to
the minimum 3-1/2 full thread requirement, the length of thread at conduit entrances must also be at least 1/4”. A 3/8” conduit entrance therefore requires a
minimum of a 0.25”/6.4mm wall thickness. For aluminum box and cover, add suffix —A.

† Type DTX boxes must have a minimum of 3-1/2 full threads at all conduit entrances. The “Max. Conduit Size” listed herein indicates the maximum drilled and
tapped conduit entrance which can be machined into the four unbossed sides of a given box to provide these 3-1/2 full threads. If larger conduit openings
than those listed herein are required, bosses can be supplied by us at an additional cost to provide the minimum 3-1/2 full thread requirement. In addition to
the minimum 3-1/2 full thread requirement, the length of thread at conduit entrances must also be at least 1/4”. A 3/8” conduit entrance therefore requires a
minimum of a 0.25”/6.4mm wall thickness. For aluminum box and cover, add suffix —A.
