No - here is a couple of previous similar questions with responses on using foam -

If coming in around the conduit (down the ouside of the conduit or pooling on top of the meter box and running in) then regular long-life caulk (silicone sticks better to metal) should seal that off.


If coming down INSIDE the conduit, then either the conduit has a break or loose connection, the weatherhead (assuming overhead service) is broken, the weatherseals around the wires where they go into the weather head are bad or cracked up with age and dropped out, or the wiring is not draped down before the weatherhead (should droop down then go UP into the weatherhead to keep water from running along the wires into the weather head).


If coming down inside the conduit, you need to have an electrician repair that and at the source, not at the outlet because that would back up water in the conduit. Call utility to see where their demarkation point is (where their responsiblity ends) - some have responsibility to the meter, but most terminate at the splice outside the weatherhead or at the pole so in that case you would have to call an electrician yourself at your cost.


Do NOT try doing this yourself - first commonly the wires have live ends in the splices or may even be bare wire coming from the pole so you could become a crispy critter on an episode of the Wiley Coyote/Roadrunner show (or a very short-lived YouTube sensation), also regular household caulk (especially silicones) can dissolve the insulation on the wires - should be corrected by a pro with the right materials.


And of course the box and wiring inside should be inspected for corrosion which could be dangerous - if the water was getting at the wires the connections should probably be taken apart and remade to ensure you do not have corroded bus connections which could overheat and cause a fire.


Cost anywhere from probably minimum service charge of $150-250 if utility will not do it for free (assuming two men since involves live-wire work), and on up if there is damage from the leakage, to poentially maybe $600-1000 range if this has been going on for so long that the panel/box is so rusted it needs replacing.
