My light junction box is under my deck steps just sticking up out of the ground. We are going to concrete under there when the pool is finished. There are 4 wires going into it and I think concreteing around them will make the concrete crack, let water get under the concrete etc. Also we will be spraying water under there to wash down the deck because it all runs together. Isnt that dangerous? What about it just being loose, shouldn't it be attached to something? Please Help!
