Outdoor Junction Box 5-Pack

The BONAEVER P68 is a five-pack of IP68-rated M16 junction boxes designed for outdoor, underwater and underground cable connections. Each unit accepts a 3.5–10 mm cable range and carries a 400 V 17.5 A rating for live, neutral and earth conductors. The kit suits electricians, landscapers and DIYers who need reliable weatherproof splices for garden lighting, billboard displays or street lights.

Dual Rubber Rings Per Box

Every connector ships with two rubber-ring sizes covering 3.5–7 mm and 7–10 mm cables, so one box handles both thin and thick leads without extra parts. The built-in clamping nut locks the seal once the single required screwdriver tightens the terminals. Users must verify all nuts are snug after assembly to maintain the IP68 barrier.

PA66 Housing V-0 Flame Retardant

The PA66 body operates from -40 °C to 105 °C and meets UL, TUV, SAA, CE and RoHS standards with a V-0 flame rating. M16 threads and a compact form factor allow mounting on poles, in tunnels or directly in shallow water up to 3.5 m depth. Installers needing larger wire gauges or higher pole counts will require a different connector series.

Questions about this item

How often should I replace the rubber sealing rings on the M16 connectors to maintain the IP68 rating?

Inspect the built-in rubber rings whenever you re-open a connector; replace them if they show cracks or permanent compression so the IP68 seal stays reliable.

What is the maximum continuous current the 3-pole M16 terminals can carry before the PA66 housing reaches its 105 °C limit?

The terminals are rated for 17.5 A at 400 V AC; staying at or below that current keeps the PA66 body within its -40 °C to 105 °C working range.

Does the PA66 junction box get noticeably warm when running at 17.5 A all day in direct sun?

At the rated 17.5 A the V-0 flame-retardant PA66 housing stays within its 105 °C limit, so surface heat remains modest even during continuous outdoor operation.
