strung together this:

If you're not sure about this, you may want to do some more reading and
finding-out about electrics before tackling such jobs; 240V with
kilo-amps of Prospective Fault Current is no joke...

Now correct moi if I'm wrong but didn't someone say on here the other
week that substations were on fuses of 300 amps or thereabouts?....

That may be but the instantaneous current that flows immediately prior
to a circuit protective device operating is many thousands of amps.
