Learn more by watching our NLS 66CV520 | 5 Pin 20Amp Switched Socket Outlet IP66 30494 video.
The NLS 66CV520 is a 5 pin 20 amp industrial switched socket outlet rated 500V, designed for industrial and small commercial applications. The 66CV520 provides secure switchable power on a 20A rated circuit, with IP66 protection against dust and water ingress. It complies with AS/NZS 3123 standards and is certified for use in both indoor and outdoor industrial environments.
Industrial jobsites and small commercial installations require outlets that withstand challenging environments without sacrificing security. The switchable design on the 66CV520 lets tradies isolate power at the outlet itself, reducing the need to run back to the switchboard for controlled shutdowns. The IP66 rating handles dust, moisture, and splash zones that would compromise standard indoor outlets. Many contractors specify this series across multi-unit installs and retrofit work where cost and reliability need to balance.
Electricians value the 66CV520 for its robust industrial construction at a fair price point. The lockable feature adds security on active jobsites, and the five round pin design is standardised across industrial plants, so plugs and adapters are interchangeable with existing equipment. The screw terminals accept cable from 4 to 16mm², suiting most site runs. Stock rotation is straightforward: the 66 series forms the backbone of industrial outlet ranges, so the NLS 66CV520 sits alongside compatible plugs, wall plates, and extension leads.
The NLS 66CV520 is not suitable for indoor domestic use where 10A outlets are standard. It is rated for industrial and commercial installation only, not for domestic kitchen or lounge power points. The 66CV520 is not weatherproof enough for fully exposed outdoor roof-mounted or submersed applications; use a fully waterproof industrial enclosure outlet in extreme flood or submersion risk areas.

Installation of the NLS 66CV520 must be carried out by a licensed electrician. The outlet requires a suitable conduit entry, correct terminal arrangement (earth to the top pin on a five pin industrial outlet), and proper circuit protection on a 20A MCB or RCD. Testing and commissioning under AS/NZS 3017 is mandatory.
The 66CV520 includes a switchable function at the outlet itself, allowing power isolation without accessing the switchboard. This is useful for security and jobsite efficiency. The IP66 protection is also integral, whereas some industrial outlets are IP20 standard and require external weatherproof enclosures. The five pin configuration and 20A rating match most industrial standards.
Yes. The five round pin design is an industrial standard, so any five pin industrial plug will connect to the 66CV520. The 20A rating matches standard industrial power tool plugs and machinery couplers. Verify voltage and amp rating on your equipment match 500V 20A before plugging in.
The 66CV520 screw terminals accept cable from 4 to 16mm². For a 20A circuit, cable size depends on run length and conduit type. Standard practice is 6mm² for runs up to 30 metres on a 20A circuit. Consult your licensed electrician for your specific site run length and installation method.
The lockable outlet has a slide latch that prevents the plug from being withdrawn without intentional release. Simply slide the latch across to engage it after the plug is fully inserted. This is a physical latch only and does not electrically isolate the outlet; use the switchable button to cut power before removing the plug.
The 66CV520 is supplied with two 25mm and one 32mm threaded conduit entries on the back. These allow underground runs and surface-mounted conduit to connect directly, reducing the need for junction boxes or adapters on the outlet face itself.
The NLS 66CV520 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
