Default Waterproofing electrical connection


"Peter" wrote in message
...
I have a drainage pump in a manhole which connects to armoured cable in a
box at the top (inside) the manhole.
All is well until the pump breaks down, water level rises and the box does
not keep the water out.
Local electric store says they have nothing to help so I wondered .....
can I literally fill the box with silicon to solve the problem.
At the outset the connection should have been made above ground ( a wall
about 8 feet away) but alas, there is now not sufficient cable to play
with meaning the connection has to remain inside the manhole.
Any help appreciated.


looking at the price of pumps, the cost of wp boxes and the inconvenience of
having perhaps a compound filled box in the manhole, maybe a new pump is the
best option. How have you solved the breakdowns you report?
