Frequently Asked Questions

What is included in a Rain Bird WC100 / RB-WC100 pack?
Each pack contains 100 complete connector systems — a red twist-on wire nut plus a silicone-filled
direct-bury tube for moisture-sealed splices.

Is the Rain Bird WC100 rated for direct burial?
Yes. The WC100 series is UL 486D listed as a sealed wire connector system and is intended for
direct-bury irrigation and two-wire connections when installed per local code.

What wire sizes work with Rain Bird WC100 connectors?
Rain Bird WC100 connectors accept wire combinations from 22 AWG to 8 AWG (solid or stranded) and
support connections from 24 VAC up to 600 VAC.

How is Rain Bird WC100 different from ordinary wire nuts?
Beyond the twist-on nut, WC100 adds a silicone-filled tube, strain relief, and UV-protected materials
so splices stay sealed underground and hold up better when staged in sunlight before install.

Can I use WC100 on decoder / two-wire irrigation systems?
Yes. Rain Bird positions WC100 as ideal for all two-wire control systems, decoder splices, and
general irrigation valve and sensor wiring within the published wire and voltage ranges.
