Blackburn RS4545 – Frequently Asked Questions
1) Is the Blackburn RS4545 splice insulated, or do I have to cover it after crimping?
The RS4545 is a bare compression splice with no insulation on it, so the joint has to be covered in the field. Plan on heat shrink tubing or tape rated for the conductor voltage as part of the install.
2) Does the Blackburn RS4545 splice meet ANSI C119.4 for underground and service entrance connectors?
It passes the requirements of ANSI C119.4, the standard for electric cable connectors used with aluminum or copper conductors. That is the rating inspectors and utility specs usually call out for a service entrance splice.
3) How many conductors does the Blackburn RS4545 service entrance splice join?
Two. It is a straight two conductor splice, one cable in each end, crimped with a compression tool. If you need to tap a third run you need a different connector body, not this one.
4) What size is the Blackburn RS4545 splice barrel and will it fit in my meter socket or pull box?
The RS4545 measures 4-1/2 inches, so allow for that full barrel length plus your insulation cover and cable bend inside the enclosure. In tight meter sockets and shallow gutters that length is usually the limiting factor, not the conductor size.
5) Can I use a mechanical set screw connector instead of the Blackburn RS4545 compression splice?
They do different jobs. A compression splice like the RS4545 is crimped once with a die and tool and is not re-enterable, which is what utilities and inspectors generally want on a buried or permanently sealed service entrance joint. A mechanical set screw connector can be taken apart and re-torqued, which suits accessible panel and gutter work but is often not accepted where a C119.4 sealed splice is specified. If your spec calls out ANSI C119.4 performance, the compression splice is the one to use.
6) Is the Blackburn RS4545 sold individually or in a bag of connectors?
Sold each, one splice per unit, so order one per joint. Remember a two conductor service run needs a separate splice for every conductor being joined.
7) What is the exact part number and origin of the Blackburn aluminum service entrance splice 500-450?
Blackburn RS4545 is the manufacturer part number, described as an aluminum service entrance compression splice, 500-450. It is made in Mexico.
