This manual provides instructions for safe installation of the InterLock Kit onto a
Square-D panel. The back plate sits securely on the face of the panel cover while
allowing the front plate to slide between the main and generator breaker positions. The
InterLock Kit will only allow one of these breakers to be in the “ON” position meeting
the requirements of Article 702 of the National Electric Code ANSI/NFPA 70. The
installation of the breaker retaining strap meets Article 408.36 (NEC 2008).

SAFE THESE INSTRUCTIONS
INSTALLATION INSTRUCTIONS
1) Disconnect power to the panel
2) Separate plates. Remove backing from double stick tape. Align back plate (P-
5411) with the top of the first and second breaker slot (1,2 slot) on front of panel
cover and around the opening for main breaker. See Figure I (Do not drill holes
at this time)
3) Remove panel cover
4) Relocate breakers from slots 2 ,4 and 6 (top 3 spaces of the right breaker column)
utilizing piggyback breakers as necessary to create the needed spaces
5) Install generator breaker in the 2,4 slot.
6) Temporarily remove breakers from the 5,6 slots. Loop the breaker retaining strap
(S-1004) around breakers 1,2,3,4 - ½” from the front face of the breakers. Align
the head of the retaining strap at the top right of the number 2 breaker and tighten
the strap. See Figure IB. Cut the tail of the retaining strap approximately 2
inches long and install Notice Label (S-1005) around tail. Reinstall the breakers
in the 5,6 slots. Verify that the retaining strap keeps the 2,4 breaker in place by
attempting to remove the breaker.
7) On suitable surface use included 11/64 drill bit (H-5415) to drill out holes in the
panel cover through the predrilled holes in the back plate (P-5411)
8) Use file to smooth surface around holes and remove the burrs on back of panel
cover. On the back of the panel cover file away paint to allow entire screw
head to sit with metal to metal contact. The binder screws (H-5414) must sit
flush with the back of the panel cover
9) Insert binder screws (H-5414) through the back of the panel cover, back plate (P-
5411), and front plate (P-5412). Use the binder post (H-5413) to attach to front of
binder screws (H-5414). Handhold binder post (H-5413) while using screwdriver
to tighten the binder screws (H-5414). The front plate should slide easily and the
back plate should sit firmly. Be careful not to over-tighten.
10) Set generator and main breakers in the “OFF” position and reattach panel cover
Figure I Figure IB
11) With the panel cover firmly in place test the InterLock to make sure that it
transfers easily between positions. BOTH BREAKERS SHOULD NOT BE
ABLE TO BE IN THE “ON” POSITION AT THE SAME TIME. Even with
moderate pressure you should not be able to engage both breakers at once.
12) Apply thread lock (H-5416) to all four binder post (H-5413) as per instructions
included with the thread lock
13) Attach labels as shown in Figure II
14) Reconnect power to the panel
