The WPMS04/616 is a pre-built IP65 plastic garage enclosure featuring a 100 A main switch incomer and twin B Curve MCBs rated at 6 A and 16 A. Designed for lighting and socket circuits in garages, workshops, or outbuildings, it offers safe, weatherproof distribution in a compact, easy-to-install enclosure.
Installer Tip: The 6 A / 16 A combination suits most garage or shed setups — one circuit for lighting, the other for sockets. Use an upstream RCBO or RCD incomer to provide full fault protection if not already supplied.
- 100 A double-pole main switch for total circuit isolation
- 2 × B Curve MCBs: 6 A (lighting) + 16 A (socket power)
- IP65-rated plastic enclosure – weather-resistant and corrosion-proof
- Pre-fitted earth and neutral bars for quick on-site wiring
- Compact footprint: 140 mm (W) × 208 mm (H) × 95 mm (D)
- Compliant with BS EN 61439-3 and BS 7671 Amendment 2
| Model | Main Switch | MCB Configuration | Ingress Rating | Common Use |
|---|---|---|---|---|
| WPMS04/616 | 100 A DP | 6 A + 16 A | IP65 | Lighting + sockets |

This garage unit is pre-assembled, tested, and ready to mount — ideal for quick, compliant installations in outbuildings or external spaces where a simple weatherproof distribution point is required.
Can this be installed outside?
Yes – the IP65 rating allows for safe use in garages, workshops, and outdoor areas, provided glands are sealed properly. For harsher conditions, see our weatherproof sockets and switches.
What’s the difference between this and the 20 A or 32 A versions?
The WPMS04/620 and WPMS04/632 use larger MCBs for higher current socket or equipment circuits.
Does it come with earth and neutral bars?
Yes – both bars are pre-fitted inside the enclosure for fast on-site wiring.
Does it include RCD protection?
No – this version uses a main switch incomer. For RCD-protected boards, see our RCD garage enclosure range.
Is the enclosure pre-wired?
Yes, it’s assembled and internally configured; you only need to terminate incoming and outgoing cables.
