Meets or exceeds:
Lock fits in slotted channel above T or Hook Bar providing lockout until removal
5-inch T Bar
3 ½-inch Hook Bar
(bars are trimmed to fit for breaker throw and panel center measurement)
Does the panel have a V-shaped valley down the center?
Is there a metal holder attached to the door that would encroach into the panel depth?
Note: Power/Bloc is provided as a High Profile model for panels with a depth of ¾″ or more or a Low Profile model for panels with a depth of 9/16″ or less. *This measurement is critical.Power/Bloc Measurement/Observations
Dispense small amount of adhesive until two part adhesive feeds evenly prior to adding mixing tube; attach mixing tube to adhesive firmly and twist for secure fit
Align mid-point of first two slots in Power/Bloc channel with mid-point of top breaker; center Power/Bloc channel in panel
Place Power/Bloc channel in panel and hold until set in place –2-3 minutes working time – full cure in 24 hours (follow placement instructions supplied with kit)
Quick release painters tape or masking tape may be used to hold channel in place until adhesive is set.
If there is more than one Power/Bloc channel to accommodate the length of a panel, attach the longest part on top and place the additional piece adjacent to the first piece.
Release pressure, discard mixing tube and recap adhesive at end of installation or during significant time delay in installation process. Adhesive setting up in mixing tube may be delayed by wrapping in a damp cloth and placing on ice pack during multiple kit installation process. Replace mixing tube when adhesive begins to harden in tube.
Placement may be horizontal or vertical
Before trimming – T-bars are 5″ long Hook bars are 3½″ long
Attach small strip in proper location for Stop/Loc bar to push against small main
* Note: Materials will be in place to allow future conversion to a full lockout procedure, if desired.
Standard bar length is 8″ Available in other lengths upon request. Shims may be required.
Panels with center width
over 3″ requiring
(2) Power/Bloc channels
Power/Bloc may be attached directly to molded case circuit breaker with 3M DP-805 adhesive
Multiple circuits may be locked out with minimal locks, if desired. Contact factory for details.
