Shed Electrics

[stefan4782]

I have got a outhouse (SHED) its got 5 double sockets 3 12v spot lighs and a outside light plus a 2kw heater (Will replace with 500w heater) there was 2.5mm supplying the shed now I have taken it out I was going to use Newlec NL6943XLH Cable, Black, 25m, Copper 4mm², Three Core with a Crabtree RCBO Type C, 40A, Single Module.

Would this be okay to use or would the 2.5mm be okay?

is the cable you plan to use to be burried?...is it armoured?....whats the earthing arrangements here?....whats the bonding like?.....any additional protection (RCD/S)?

 

[Marvo]

The answer to your question depends largely on what you're going to plug into your 5 sockets.

 

[ipf]

Did you buy the shed from a shed ?

 

[stefan4782]

The shed has 5 double socktes theres a 32" LCD TV and PC, games console 2kw heater (may get a 500watt heater) and 2.1 surround sound set plugged in there may also be a small pond pump. There are 3 12v spot lights also and a normal energy save outside light the cable is 4mm SWA cable it may not be burried there is a consumer unit in the shed with a 32a mcb and a 6a mcb

Are you getting an electrician in to install or have you got the quals and test equipment to do this job yourself?

 

[stefan4782]

I done level 1 2 and 3 at college + my granddad is a qualified electrician but he lives to far away so ill do it then he can come check it

 

[Paul.M]

Ok stefan just do basic cable calcs. What's going to be the flc of the shed? What's the distance of the cable run for volt drop? What earthing arrangement is it? Etc etc.

 

[stefan4782]

iv been abit lazy and done a volt drop calculation on tlc website it has come up with 1.5mm cable thats aint right

 

[Paul.M]

Where's your books? Or is that the lazy bit.

[Engineer54]

I'm going to have to ask!! ...Why are you having this shed on a TT system??

Oh, and how about giving some answers to questions that has been asked on your cable, like is it being direct buried etc???

It's the economy I blame. Can't export anything at the moment because of the downturn in the financial situation
