Looking at the forecast, it appears we may be charging in heavy rain tonight at an RV park. I'm soliciting any data/opinions on whether it is OK to charge in the rain and to leave the UMC out in the rain all night. I know rain water isn't highly conductive, not like sea water, but I'm more wondering if exposure to rain water might result in corrosion of the 14-50 adapter or mess up our expensive UMC. I'm hoping the plug end of the UMC will be covered by the charge point cover, and the Roadster end looks pretty water tight once attached. I have a feeling this might be filed along with the time I asked MPT if the magnetic field from the motor would wipe my laptop hard drive. But thanks in advance for any advice.
