RCCB/Fused Spur

by kbrownie » Sat Jun 23, 2007 8:14 pm

If I was opperating an RCCB on an appliance, would I put the spur between the supply from the Consumer unit and RCCB or Between RCCB and appliance. The instruction say use a fused spur in but not where Can anyone help me?

Sorry for delay, Forgot about this one, been on my jolly's? Bit cheekie really! It's a question on an assignment from college, i'm not cheating it was end of year and just a bit of prep for next year. Installation of a bathroom with electric shower and whirlpool bath. Old cartridge type fuse board, no RCCB on board. Question not that clear on paper. I assumed that both shower and whirlpool should be on seperate circiuts (Circuits of thier own). The shower would be zone 2 and the whirlpool not in a zone as the wiring would be under the bath, which is enclosed. Fused 13 amp spur to RCCB then to whirlpool. Is that right you can mark me if you wish.
Cheers KB

SEPARATE CIRCUITS WITH THIER OWN MCB S BASED ON
CALCULATIONS TO SELECT PROTECTIVE DEVICE SIZE AND
CABLE RATING .
RCD 30 MA PROTECTION NORMALY , BUT CONSULATION
WITH DESIGN INFORMATION AND PRODUCT GUIDES WILL
RECOMMEND RCD SIZES.
U HAVE TO WORK OUT WHETHER U WOULD UPGRADE
MAINS BOARD TO A SPLIT VARIETY TO GIVE U YOUR RCD WAYS.
I FIT AN RCD SPUR FOR THE SPA BATH IF 13 A RATED .
OBVIOUSLY YOUR BONDING MUST B LOOKED AT TOO, AS THIS IS THE
MOST IMPORTANT FACTOR. INTEGITY OF EARTHING IS PARAMOUNT
FOR OPERATION OF AN RCD.

So bonding beneath bath, supplimentry from junction box connecting supply to spa, onto both hot water and cold water feed and metal bath support/legs. Would that be okay. Shower bonded to say emmerson heater. using 4 or 6mm earth.

Cheers your a star
