Is it safe to  put expanding spray foam  around electrical wires?

The electric wire coming into the garage  from outside is fed through  a tubing . Noticed  water coming  through the tubing when it rains,  and  coming inside . Needs sealing.  Would the expanding foam  be safe  enough to use?

I wouldn't. I've seen it more or less eat through the insulation on cables after a while, if it's a steel wire armour cable you might be ok but I still wouldn't use it personally. Is expanding foam even waterproof anyway?
Why not just use silicone?

Never thought of that . Must check if I have some. That would be  safe enough to use, I take it?

Yeah it's fine to use.
