Blackburn E-8H-25 – Frequently Asked Questions
1) What wire sizes does the Blackburn E-8H-25 split bolt connector take?
The E-8H-25 is rated for 8 AWG stranded down to 10 AWG solid conductors. It's a tap/splice connector for copper branch and grounding work in that range, so if your run is 6 AWG or larger you need a bigger split bolt in the series.
2) What is the E-8H-25 split bolt made of, and can I use it on a ground wire in a damp location?
Silicon bronze alloy, which is the standard material for direct-burial and damp-location copper grounding splices because it resists corrosion and galls less than plain brass under torque. It's a copper-to-copper connector, so don't use it to splice aluminum.
3) Do I need to tape or insulate a Blackburn split bolt connector after installing it?
Yes. A split bolt like the E-8H-25 is a bare mechanical connector with no insulation or cover included, so any splice on an energized conductor has to be taped or fitted with an insulating cover rated for the circuit voltage. Bare equipment grounding conductor splices don't require it.
4) Can I splice two different wire sizes together with the E-8H-25?
Yes, within its range. The 8 AWG stranded to 10 AWG solid rating means you can run a tap of one size to a main of another as long as both fall in that window, which is the usual case for a 10 AWG ground tap off an 8 AWG run. Both conductors must be copper.
5) Is the Blackburn E-8H-25 sold individually or in a box?
It's sold each, so order the exact count you need for the job rather than a carton quantity.
6) What part number should I give my supplier for this Blackburn split bolt?
Blackburn E-8H-25 is the manufacturer part number, and it's also the model designation on the connector itself. That's the number to quote for an 8 stranded to 10 solid copper split bolt.
