Blackburn RS403 – Frequently Asked Questions

1) What conductor sizes does the Blackburn RS403 service entrance splice take?
The RS403 is sized for 400-336 kcmil aluminum down to 4/0, per the product designation AL SERVENTR COMP SPLICE 400-336 4/0. It is a two-conductor splice, so it joins one run to one run, not a multi-tap. Match your actual conductor size to that range before crimping, since a compression splice is a one-shot install.
2) Does the RS403 come insulated, or do I need to tape or sleeve it?
It ships bare. The RS403 has no insulation on it, so the splice has to be insulated in the field, typically with heat shrink, a cold shrink sleeve, or tape built up to the cable's rating. Budget for that material on the job.
3) Is the RS403 a compression splice or a mechanical set-screw connector?
Compression. The RS403 is installed with a crimp tool and die, not a set screw or bolt, so once it is pressed on it is permanent. If you need a connector you can back out and re-terminate, a mechanical set-screw splice is the type to look for instead.
4) Can the RS403 be used to splice aluminum service entrance conductors to copper?
The RS403 is an aluminum-bodied service entrance compression splice and it passes ANSI C119.4, which is the standard governing connectors used between aluminum and copper conductors. Follow the manufacturer's instructions on compound and die selection for the combination you are joining.
5) How long is the RS403 splice body, and will it fit in my meter can or pull box?
The RS403 measures 6 inches, so allow for that plus insulating sleeve and bending room inside the enclosure. In a shallow meter socket or a tight service gutter, that length plus the cable bend radius is usually the limiting factor, not the conductor size.
6) Is the Blackburn RS403 sold individually or in a bag?
Each. One RS403 splice per unit, so order one per conductor you are joining. On a three-phase service with a neutral, that is four pieces for a single splice point.
