I normally just turn an empty chlorine bucket upside down and place it over the Power Box. It keeps rain out and have had no problems for years with this method. You might want to make sure you wash the bucket out before using it.

Not weatherproof, which I think is a terrible design flaw.
I keep the transformer under a table on a cinderblock just in case a storm rolls in. But always put it in a shelter when not using it...
