Qualified Electrician question

[alistairb]

Hi as a practising self employed sparky conractor....the rule is any thing in zone 1 has got to be selv.......zone 2 can be within Bs 7671 mains voltage and not required by BS7671 to have and RCD as it is classed as FIXED Equipment therefore a diosconnec tion time of 5 SECONDS and NoT 0.4 seconds............although an rcd would be advisable but NOT mandatory.......yet............


My Qualifications......well.........City n guilds in electrical installation, Inspection n testing, BS7671, Design n Installation, HNC in Electrical in Design and installation and more important im a previous Inspector for the NICEIC on properties from a bungelow to a well factories, warehouses n yes 20 yrs experience....

Safe diving......

hi...PS...ALL caravan parks ARE required by Regs to have a RCD controlled Supply whether it be a static or Tourer and should be connected by means of a 16 amp 3pin plug....

My comment was in relation to them carrying out the work

A static caravan is classed as a temporary structure & doesn't even need to comply to building regs ! Stupidly nor do the services connected to it , one site has 2 inchs of gravel over the sewer, water & electric cables ,all in the same trench

So would I but I own the caravan park ( I know stupid me ! )

Id check what the NICEIC say on the SELV fan. Through bitter xperience of arguing your point i.e no SELV for the inspector who I got down to qualify my statement to the building contractor said it needed to be SELV in zone 2 and the bitterest pill was that the fan only strayed into zone 2 by 5mm.



the works would be done with Mini trunking anyway nasty fecking white plastic stuff even when done to a high standard.

Here is an interesting discussion for y'all.

The fan fitted (which is knackered) is Mains Voltage & IP24 rated but the electrician says this is illegal & it must be low voltage but the original was fitted by the manufacturers & the caravan is only 3 years old . Is he correct or is there some different ruling due to it being a caravan ?
The fan is operated by the pull cord for the light .
TIA

C,mon chaps,,,he needs a new fan so the sensible answer would be to replace it with a low voltage unit,,easy done,, cheap and job jobbed !!!

agreed, if the van its in isn't where you live just wang it in as a SELV, there will likely be an isolator outside the bathroom that will have a neutral there so no nasty mini trunking required.

you can never over egg the pudding with safety especially in bathrooms where elastictrickery is involved.


wait till july when all new wiring needs to comply with the new version then the fun will start.

the last lot of reg changes were driven by the cable manufacturers to sell more copper, this change is driven by consumer unit manufacturers to sell a shed load of RCBOs .


alistair I have the guide to consumer units and the new regs from Hgaer as a PDF PM me with an email addy and I will send it, makes for 'fun' reading.

no it wouldn't because the manufacturers are still producing them with mains voltage fans .As DSD said the way to do it is minitrunking & low voltage . But you have just paid £70,000 for a new static caravan & somebody goes & rips out the mains fan & sticks a load of minitrunking round it !
I know what I would say
