Learn more by watching our NLS 30037 | 5 Hole Neutral Link Black Housing video.
The NLS 30037 is a neutral link termination bar for switchboards and meter enclosures, rated 500V 100A. It provides five separate connection points for incoming cables, numbered for identification. The 30037 sits inside a cabinet or board and is used to consolidate neutral connections where space is limited.
Neutral links are a compact alternative to traditional busbar termination. Installation requires a licensed electrician to open the switchboard, position the bar on the mounting studs, and terminate the cables using standard crimp or screw-terminal techniques. Five-hole links are common in residential and small commercial installations where a single consolidated neutral point serves multiple circuit groups.
The 30037 reduces clutter inside the board by gathering neutral cables in one place instead of scattering them across multiple termination points. This keeps the installation tidy, aids future troubleshooting, and makes cable identification straightforward since each terminal is numbered. Licensed sparkies routinely stock neutral links because they save installation time and space on every job that needs neat, consolidated neutral runs.
Verified Sparky Direct customer reviews: NLS 30037 (30037)
"Good product, exactly what was described." — Nick
(30037)
The 5-hole NLS 30037 has five connection points; the 7-hole has seven. Choose based on how many neutral cables you need to consolidate. Five holes suit typical residential switchboards; seven holes are used in larger boards with more circuits.
The 30037 is rated for both switchboards and meter enclosures. Install it inside any cabinet where consolidated neutral termination is required, as long as there is space for the 66mm × 45mm footprint.
Yes. Each of the five terminals is numbered 1 through 5, making it easy to label incoming cables and identify connections during testing or future maintenance.
Three terminals accept cables up to 16mm² (5.5mm studs), and two terminals accept cables up to 25mm² (8.0mm studs). This mixed configuration suits typical residential installations where most circuits run on smaller cable and one or two larger circuits need heavier gauge.
Yes. Neutral link installation requires opening a switchboard or meter enclosure, which is licensed electrical work in all Australian states. Installation must be carried out by a licensed electrician or registered training provider.
Yes. NLS products carry a one-year domestic and commercial warranty covering manufacturing defects. Warranty starts from invoice date and does not cover damage from incorrect installation or physical mishandling.
