Sta-Kon RL727 – Frequently Asked Questions
1) What wire size does the Sta-Kon RL727 ring terminal take?
The RL727 is sized for 4/0 AWG conductor. It is a single-size terminal, so it will not grip smaller cable reliably, even 2/0 or 1/0 - for those you need the terminal built for that gauge. Confirm the cable gauge before you crimp, because an undersized conductor in a 4/0 barrel will pull out.
2) Is the Sta-Kon RL727 rated for 600 volt circuits?
Yes, the insulation on the RL727 carries a 600 V rating, which covers standard commercial feeder and branch circuit work, motor leads, panelboards and control gear up to 600 volts.
3) Why choose a nylon insulated ring terminal instead of a vinyl insulated or bare lug?
Nylon is the insulation material on the RL727, and it holds up better than vinyl to abrasion and to the heat of a hot panel or engine compartment, and it resists cracking when the barrel is crimped. A bare copper lug gives you no insulation at all and needs heat shrink or boot added on the job. Pick nylon when the termination sits in a crowded enclosure where you want insulation right up to the crimp without a second step.
4) Should I use a ring terminal or a fork terminal on a 5/16 inch stud?
A ring terminal like the RL727 is the closed-barrel type: the stud has to come off or the nut fully removed to install it, but once the nut is torqued the conductor cannot back out sideways. A fork or spade slides in under a loosened nut, which is faster for service work but can walk off under vibration. On 4/0 power cable at a 5/16 stud, the ring is the right call - that much copper carries enough mass to shake a fork loose.
5) Do I need a special crimp tool for the Sta-Kon RL727?
A 4/0 AWG terminal is well past the range of a hand-held insulated terminal crimper. Terminating this size takes a heavy hydraulic or battery powered crimper with the die matched to the barrel. Plan the tooling before the terminals land on site, since a partial crimp on 4/0 is a heat problem, not just a loose connection.
6) What part number do I order for a 4/0 AWG nylon insulated ring with a 5/16 stud hole?
Order Sta-Kon RL727. That is the manufacturer part number, and it identifies the 4/0 AWG nylon insulated ring terminal with the 5/16 inch stud hole, rated 600 V.
7) Where is the Sta-Kon RL727 made? I have a country of origin requirement on the submittal.
The RL727 ring terminal is manufactured in Mexico, which is the value to put on a country-of-origin line for a submittal or government procurement package.
