Do I need?

[Rauer]

Right guys,
got my assessment coming up , do I need a proving unit or am I allowed to use the incoming side of the main switch?
Secondly do I need a wander lead or can I use a drum of singles!
and last but not least I can't find hsr 25!!!!-found it!!!
thanks!!

 

[trev]

No you don't and yes you can mate. You can also make your own wander lead

 

[ruston]

You only need to prove against a know source , so that should be fine. I can't see any harm making your your own wander lead up , I think most people do anyway.

 

[Rauer]

Few ! There's £150 saved!!

 

[ruston]

Just a spoonful off the gravy train though lol.

 

[Rauer]

Think I've just about got everything nessacerry!

 

[Rauer]

Apart from a van! But I'm hoping to sort that hurdle out in the next couple of months !!

 

[ruston]

You'll be fine mate , do'nt worry they need you more than you need them!

 

[Rauer]

What do they mean when they say they want to see design of installations?

 

[trev]

What do they mean when they say they want to see design of installations?

Your design calculations.

 

[ruston]

usually a drawing or a diagram plan of the installation. I think in a domestic install a well made up legend of the circuits at the CU suffices. Phone them up and ask them

 

[Rauer]

Your design calculations.

So adiabatic equations or just a case of looking in the regs book for the current carrying capacities of cable for a ring and a lighting circuit etc!

 

[trev]

The ccc of a cable is one thing but how many things have to be considered which can affect that?
Think derating you did it on your 17th
Obviously you have to think about all the cables you are installing mate

 

[Rauer]

I appreciate the derating factors like ambient temps and grouping etc, am I supposed to be keeping all this in a record for every job I do? And is there some sort of form to fill all this info on or do I just magic something up on a spreadsheet!

 

[Johnny-G]

Just tell your assessor that you used the OSG for any circuit designs.

 

[trev]

I'd keep a record of it mate, whether that be a hard copy or a spreadsheet on your hard drive is a matter for you and your scheme provider, ring them and ask them what they want. It's all part of the process that proves you have done your job correctly. Who are you going with? post that up and you'll get advice from guys who are registered with that provider because I'm not scammed up. The vast majority of my work is commercial with like for like replacements in domestic situations. For big jobs I team up with a mate of mine who is scammed up

 

[Rauer]

I've signed up to elecsa! Got Russell Prestidge, have heard he's a nice bloke!

 

[ruston]

Just looked the regs up for common rules (how sad is that) 514.9 Diagrams and documents when you get the chance to look. These items should be available to future testers , It does say for simple installations the foregoing information may be given in a schedule. A durable copy of the schedule relating to a distribution board shall be provided within or adjacent to each distribution board,

 

[Rauer]

So in other words a db schedule will suffice! Which I think is what you said earlier!

Check the reg to get the full gist and check with Elecsa , I'm not sure what they want, but it satisfies the regs .
