okay so you can see we've got the electric shower now and so i've took the front cover off
and i've done a Zs earth fault loop impedance test and that came up as about 0.76 ohms so that's okay
so it's not live at the moment i've isolated it so i do like on the showers just to check now just
check the termination tightness now you've seen there i've just slightly turned it and already
i've turned that about almost one turn to the CPC
and again the line we've done the same so so you can see up there it was not perfectly tight
now on this one like so it's not live at the moment because i've got it isolated
i actually did when i checked the tightness of these terminals there
normally i should have done that at the end but i did that on purpose
to show you that that's how i found it and how i found it it wasn't perfectly tight
now i've just made a bit of a loop on this neutral which means that it's going to slightly
loosen up the termination side so i'm going to have to check it again but the idea of that is
i'm going to put the front cover back on
so the front cover back on and basically that's now connected i haven't put the screws in so
the isolation is down here so you can now see it's live let's come back to the shower
i'm going to turn the shower on now it's electric shower so there's the eco mode or there's the
maximum mode so the maximum mode this mode here is where it uses the full um output of the shower so
again i'm just going to take the front cover off again we are working live now so we do have to be
careful now i don't know if you can see in there but it says in there between 2 to 240 volts
8.7 to 9.5 kilowatts so it's actually a 9.5 kilowatt shower and you can see there it says 9.5
now one thing that you might notice is the twin earth cable they've used it's a six mil
and i'm really if you're gonna use a nine and a half kilowatt shower it should be a
ten mil so i've got my little camp on meter i'm just going to put it around the neutral
and you can see there that's using 40 amps
so 40 amps it's a 40 amp circuit breaker so that's okay but it's not ideal to be 40 amps on a 6 mil
so cable just talk over that again so we've put the ammeter onto the neutral and it's read about
40 amps now it's protected by a 40 amp circuit breaker so that's okay but what isn't okay is
that this is a six mil cable and so i think off the top of my head the maximum current that a six
mil can carry is around 46 amps um i think that's if it's a if it's clipped direct to the surface
well this one isn't clipped it's embedded it's in contact with insulation it's a good 10 meter run
so again it's another issue that we find with electric showers they've got their original
six mil cable installed but then they've been upgraded to a nine and a half from something
like a 7.2 or 8.5 or whatever the shower's been upgraded but the cable hasn't so that's
something that's going to go down as a bit of an issue on the on the EICR that will pick that up
and recommend maybe to downgrade the shower or upgrade the cable
