16A IP67 Waterproof Heavy Duty Extension Lead 230V 3 Pin 2.5mm² H07RN-F Rubber Cable

This is our heavy duty 16A IP67 extension lead for industrial, construction and outdoor power applications where a standard IP44 lead may not provide enough protection.

Built using genuine Mennekes PowerTOP® Xtra connectors and 2.5mm² H07RN-F heavy duty rubber cable, it is designed for demanding environments where cables may be exposed to rain, mud, dust, dirt and regular handling on site.

It is well suited to construction sites, industrial maintenance, plant equipment, temporary site supplies, outdoor machinery and other applications where reliability and environmental protection matter.

Proper cable, built for harsh conditions

We build these using 2.5mm² H07RN-F heavy duty rubber cable, selected for its flexibility, durability and resistance to demanding working conditions.

H07RN-F is widely used for industrial and temporary power applications because it remains flexible while providing a tough outer sheath suited to regular handling and outdoor use.

The cable meets the relevant harmonised standards and is UV resistant and flame retardant, making it suitable for both indoor and outdoor applications.

Using 2.5mm² cable helps reduce voltage drop while still keeping the lead practical to coil, transport and deploy.

Mennekes PowerTOP® Xtra IP67 / IP69 connectors

We use genuine Mennekes PowerTOP® Xtra connectors at both ends of the cable.

The PowerTOP® Xtra range is designed specifically for demanding industrial environments and combines robust construction with a high level of protection against dust and water.

Both the plug and connector are rated IP67 / IP69, making them particularly well suited to outdoor and harsh-environment applications when correctly connected and used as intended.

Why IP67 / IP69?

Standard 16A industrial connectors are commonly rated IP44, which is suitable for many general-purpose applications.

For harsher environments, the higher level of protection offered by the Mennekes PowerTOP® Xtra range makes these leads more suitable where connectors may be exposed to heavy rain, dust, mud, dirt or high-pressure cleaning.

This makes them particularly useful for:

• Construction sites
• Industrial maintenance
• Outdoor machinery
• Plant and equipment
• Temporary site power
• Agricultural applications
• Workshops and yards
• Utilities and infrastructure work
• Harsh outdoor environments
• Hire and rental fleets

Built for professional site use

These are intended as working industrial leads rather than lightweight extension cables.

The combination of 2.5mm² H07RN-F cable and Mennekes PowerTOP® Xtra connectors gives you a robust extension lead designed for regular professional use in demanding conditions.

Asset marking

We supply all cables with 12cm of clear heat shrink as standard, giving you a clean and durable area for asset labels, company branding or inspection tags.

Need something different? No problem.

We know every company has its own standards.

If you need a different cable length, different heat shrink arrangement or another connector configuration, just drop us an email or give us a call.

We can build the cable to suit your requirements.

Custom configurations may add a little production time, so next-day dispatch might not always be possible.

Built and checked properly

We build these as professional working kit:

• Genuine Mennekes PowerTOP® Xtra connectors
• 2.5mm² H07RN-F heavy duty rubber cable
• Bootlace ferrules used for clean, reliable terminations where appropriate
• Torque screwdrivers used to tighten connections to the correct specification
• Every cable fully electrically tested
• PAT tested before dispatch

Length options

Available in a range of standard lengths to suit different site requirements.

Need something specific? Use our custom cable option and we’ll build it to your exact length and configuration.
