I know the OHME cable is IP54 ‘splash proof”. Do you leave it connected to the power supply all of the time or do you unplug it every time after use?
I thought it was IP54 - https://www.eviuk.co.uk/wp-content/uploads/2020/05/Ohme-Cable-Product-Manual-v1.0.pdf ?I have to, it's attached to the wall! The drainage holes stop any standing water but I was quite concerned with all the rain we've had.
It's IP55 rated so it'll be fine until you come at it with a pressure washer.
Ah, I did a quick search and ended up somewhere else showing IP55: https://www.europacomponents.com/pdfs/Ohme_EV_Datasheet.pdf
The new ones have drainage holes, bit of an initial oversight on their part.
