To Wago or not to Wago?

[TSB240]

I was shocked and stunned to see I used some chocolate block in the anchor locker, surely the wettest and most inhospitable place on the boat. Though rusted and sad looking it had stuck to it's task for a quarter of a century - since the last time I had the pulpit off.

You might have been more shocked if you had checked the actual voltage at your navigation light. I have found a 3 volt or more drop where choc blocks have been fitted in line and gone rusty. Best dimmer you could fit!

Corroded blocks are a good indication of capillary corrosion caused by moisture wicking in the cables.
Verdigris rules!

Yes, choc block is less bulky and easier to protect and waterproof, as it orientates itself with the run of the wire. Wago sticks up like a sore thumb and look a bodge though I have no doubt it is technically superior.

I use Wiska boxes. Either gell filled ones OR the junction boxes that have hole for 16mm or 20mm glands. Various sizes. Makes it easy to do IP68 connections. Inside you could use a choc block, or Wago. Bulk will be the same for both. If useing the Gel boxes I would assume smaller for a Wago. I think they are neat, waterproof, offer strain relief, reasonably cheap and, if using Wagos 221s' will never need attention again, unless you need to take them apart which will be simple.

As an aside, I have just removed my pulpit and had to disconnect the wiring to the bow light. I was shocked and stunned to see I used some chocolate block in the anchor locker, surely the wettest and most inhospitable place on the boat.

Supprised that still worked!
