Like most people I have a healthy desire to avoid electrocution. I keep thinking about the back of a kettle element on a boiler and wondering how best to protect it from water. A bit of searching gives me:
- 40 mm drain pipe with a blank. Cable glands out the blank for the power and earth leads. This seems the best overall option. If it's araldited/JB welded to the element, should be totally water tight.
- Immersion heater for a hot water tank. Bigger hole to make and probably too much current for a 13A plug. Does come with a decently manufactured cover.
- Backer element. More expensive (with a lead even more so), but electrics better protected than a salvaged element
