Hubbell Circuit-Lock General Information Manual

HUBBELL CIRCUIT -LOCK

U.S. Patent No. 5,298,701

GENERAL INFORMA TION

1. NOTICE: For installation by a qualified electrician in

accordance with national and local electrical codes and
the following instructions.

2. CAUTION: RISK OF ELECTRIC SHOCK. Disconnect
power before installing. More than one disconnect
switch may be required to de-energize this
equipment before servicing. Disconnect ALL
power supplies to enclosure before exposing
interior.

3. NOTICE: Separate overcurrent protection must be

provided in accordance with National Electrical Code
Article 220 or Canadian Electrical Code, Section B, as
appropriate. Overcurrent protection MUST NOT exceed
the ampere rating of the receptacle [ref.: National
Electrical Code® section 430-42(c) or Canadian
Electrical Code, Part 1, Rule 28-602(3)(c)(i)].

4. Suitable for use on a circuit capable of delivering not
more than 10,000 rms symmetrical amperes at the
voltage rating of the receptacle.

5. This enclosure includes a lockout provision to isolate
the receptacle and connected equipment from the
power supplied to the enclosure as a method of
compliance to OSHA Lockout/Tagout Regulation 29,
CFR Part 1910.147. The ON-OFF control knob (in the
OFF position) accepts up to 5/16 inch (8 mm)) diameter
shackle of a suitable padlock or Lockout device. This
feature does NOT isolate the power supplied to the
enclosure during internal servicing of the enclosure.

6. NOTICE: This enclosure must NOT be used as a
junction box for feed-through connections.

7. The pilot contact (if installed) is rated A600 pilot duty,
600 VAC 10A.

8. WARNING: RISK OF ELECTRIC SHOCK. Bonding
between conduits must be provided.

A.Mounting Instructions:

1. This enclosure must always be mounted vertically with receptacle end down.

2. This enclosure may be mounted for top, bottom or back conduit entrances. Bottom feed is recommended whenever
possible. Figs M1 & M2. Back feed is permitted in Type 4X applications only. Fig. M4.

3. For Type 4X and Type 12 applications, enclosure must be mounted by means of mounting feet. DO NOT drill, punch or
nail mounting holes through the enclosure.

4. Mount the feet to the enclosure using the screws provided. Tighten to 10-12 lb•in (1.2 - 1.4 N•m).

5. Mounting feet will accept up to 5/16 inch (8 mm) diameter screws (not provided). Mounting pattern is shown in Fig. M1.

6. Remove the four (4) cover mounting screws and remove cover. Switch handle must be in “OFF” position to remove cover.

7. Drill or punch hole at the desired conduit entry location:
a. 1-3/8 inch (34.9 mm) diameter for 1 inch trade size conduit hub (30 Amp).
b. 1-3/4 inch (44.4 mm) diameter for a 1-1/4 inch trade size conduit hub (60 & 100 Amp).
Molded drill spots on the outside top, bottom and back surface show the locations. Fig. M4.

INSTALLATION INSTRUCTIONS

8. Use ONLY Listed/Certified conduit hub rated for Type 4X and Type 12 applications (one supplied) such as:
RACO #1704 for 1 inch trade size (30 Amp)
RACO #1705 for 1¼ inch trade size (60 & 100 Amp)

9. Install the conduit hub. Be sure that the “O” ring is properly seated in its groove.

10. Install the grounding (bonding) plate under the conduit nut. Tighten nut securely for a watertight seal and grounding continuity.

11. Any unused conduit entrance holes must be sealed with Listed/Certified closure plugs rated Type 4X and type 12. (Hubbell
Cat. No. MICPK30 for 30A, Cat. No. MICPK60 for 60A and 100A).

12. NOTE: The metal closure plug must be grounded (bonded) back to the inside green & yellow grounding buss. Grounding
(bonding) wire connection required.

13. Use of user-installed conduit entrances above the switch are not recommended in applications where condensation may be
present in the conduit (high humidity and extreme temperature change locations). When using the top feed conduit entrance,
drip loops must always be formed as indicated in fig. M3.

INSTALLATION INSTRUCTIONS (CONTINUED)

B. Wiring Instructions

1. Select conductors having 90°C or higher rated insulation and sufficient ampacity in accordance
with the 60°C column (for 30 Amp and 60 Amp devices) or the 75ºC column (for 100 Amp
devices) of the National Electrical Code® Table 310-16 or Canadian Electrical Code Table 2.

2. CAUTION: USE COPPER CONDUCTORS ONLY.

3. DO NOT TIN CONDUCTORS.

4. Make sure the connected equipment rating does not exceed the rating of this device. See
General Information #4 regarding overcurrent protection.

5. Terminal capacity as indicated in Table 1

6. Strip conductor insulation ½ inch (13 mm).

7. Select proper wiring diagram. Loosen terminal screws. Insert conductors fully into proper terminal.

8. Tighten terminal screws to torque indicated in Table 2:

9. TAKE CAUTION THAT THERE ARE NO STRAY WIRE STRANDS.

10. Tighten the grounding buss mounting screw to 10-12 lb•in (1.2-1.4 N•m).
