can anyone tell me the stated difference between prospective short circuit current and a prospective earth fault current test

cheers certa

PSCC - Live - Neutral

PFC - Live - Earth.

pssc is the max current that can flow between Line & Neutral.

pefc max current flow between line earth.

If TNC-S using ohms law they will be the same.

so a pscc when using a earth fault loop impedance tester with 3 leads fluke i connect line to line and eart and neutral onto netral bar
and with prospective earth fault current line neutral and earth sry for being pain pal

cheers certa

If you're using a Fluke 165* then you can connect each lead to its respective cable and simply switch between the readings. I couldn't comment re other testers.

Prospective Fault Current is not the same as Prospective Earth Fault Current. PFC is the greatest of the PEFC and the PSCC.

im tryingtofind out the zone locations in a bath and shower do u no the distances to the zones and why ?

Great place here to get some other muppets to do your homework.

 

[ukpablo]

if u look in the regs or the OSG it will tell u the zone locations!

think they're now published in the Beano, between desperate dan and dennis the menace. ( page 7 )

pssc is the max current that can flow between Line & Neutral.

pefc max current flow between line earth.

If TNC-S using ohms law they will be the same.

And dnot forget between L - L

Precisely, it's the greater and the value that is recorded.

cheers pal i have borrowed a on site guide and in the book it says that zone 0 is the middle of bath or a basin i was trying to determine where zone 1 starts would i be correct in saying that zone 1 is at the edge of the bath and from ground level to ceiling at 2.25m
