Ideal 30-074 Yellow Wire Connector

The Ideal 30-074 is a standard-style twist-on wire connector rated for 600 V and copper conductors. Its yellow colour coding identifies the 18 AWG to 12 AWG range, making it suitable for residential and light commercial electrical splicing. The polypropylene shell carries a UL 94 V-2 flammability rating and meets both UL Listed and CSA Certified standards.

Tool-free installation with steel zinc-plated spring

Installation requires only hand-twisting the connector onto stripped copper wires; no special tools are needed. The internal steel spring with zinc finish grips combinations from two 18 AWG conductors up to four 14 AWG plus one 18 AWG, with a maximum single-wire capacity of 8 AWG. Over-stuffing beyond the six-conductor limit or mixing undersized wires can weaken the mechanical hold and electrical contact.

600 V capacity for branch circuits and fixtures

Rated at 600 V and a maximum operating temperature of 221 degrees F, the connector handles typical lighting, receptacle and appliance branch circuits. It runs out of headroom when conductor counts exceed six or when wire gauges fall outside the 18 AWG to 8 AWG window, so larger feeders or high-density junction boxes require a different connector style.

Questions about this item

How can I confirm the 30-074 connector is working properly after twisting it onto the wires?

After twisting the yellow connector onto the copper conductors, give each wire a firm tug to verify a secure mechanical hold and check that no bare copper is visible beyond the skirt.

What comes in the box with the Ideal 30-074 and what must I supply separately?

The package contains only the yellow twist-on wire connectors; you must provide the 18 to 12 AWG copper wires and a stripping tool.

Which version of the 30-074 should I choose for a 600 V circuit using 14 AWG and 18 AWG conductors?

The single yellow 30-074 model covers 18 AWG to 12 AWG at 600 V and accepts up to four 14 AWG with one 18 AWG, so no other version is needed.
