I have purchased a CED immersion heater timer model IMT7E. This timer
does not appear to have an Earth terminal so I am not sure what to do
with the Earth wire that comes out of the heating element? Can anyone
advise me? Thanks.

hi ken,
it is normal when connecting a timer to 'break' into the flex running
from the immersion heater to the time switch, the earth will continue
through, this probably will be a terminal on the timer witch box.
if there is not a connection then you need to make one with a 20Amp
connector, this is very important.

The timer will be either single-pole, switching only the live, or
double-pole, switching both live and nuetral. The earth should NEVER be
switched; you join up the incoming and outgoing earths in a handy
terminal in the enclosure wot the timer switch is in (either a terminal
provided in the backbox, which all backboxes sold in the last 15+ years
should have, or in extremis a single-way bit of terminal block).

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.

Well a uni researcher I was talking to a while ago didn't seem to think
it was quite like that "all" the time, but this was a while ago now....

What did he think then, the laws of physics change with the seasons...
