Rotary Isolator that takes 2x16mm?

[appspark]

Does anyone know of a rotary islotaor, weatherproof, that'll take 2 x 16mm incomers? I've got long runs out to parking bollards so they've had to size up the cable for volt drop.
I could do it with a street light cutout but it wouldn't allow them easily isolate it.
Many thanks for any help.

Thank Tel, thought i'd have to go main switch, mainly for the working space inside.

How are you going to downfuse to protect the flex going upto the lights?

Circuits only a 20 amp supply, the rotary isolator will feed a fused spur, no lights, just power for barriers.

Oh ok. Apologies.

Are you designing to the actual current or to the MCB size for the circuit?

Fortunately its not on my head, been designed by a consultant being an airport. The runs are about 150m each so its more for volt drop than anything. Basically going to be an isolator on the outside of the pillar, going through the back to a spur which will then feed the gubbins inside.
