What is the correct fuse rating to cope this lot?!?
Am installing a new Aqualisa Digital shower and it calls to be protected by a 3A fuse.
Simple enough you may say, but I am also having the same switch isolate 2No downlighters in the shower and 2 mirror demisting pads. I have installed a fused switched spur outside the bathroom which will supply all of the above via a pull cord switch in the bathroom, the idea being that I know when the mirror pads/shower supplyis on by simply seeing the lights on in the shower!! My question is: does the fuse need to be bigger to cater for the extra load? Requirements as follows: 2No. 35w downlighters 1No. large mirror pad 100w 1No. small mirror pad 25w |

If a device states it *needs* a 3A fuse then that's what you should fit. You need to know how much current the shower takes before you will know if a 3A can supply that and the others. I would imagine it takes very little and you will be OK but you need the figures to be sure. |

Mains 35W downlighters will tease a 3A fuse. You'll probably end up replacing it every time one dies. You might choose some better lighting for the room instead. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Then they might discriminate with the 13A fuse I would put in the connection unit. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |
Have checked out the spec for the shower and it states power consumption is 5 watts in the idle position and 20 watts peak during valve positioning (tis a simple electronic mixer). Does this help in establishing whether the 3A fuse is ok?
