generation meter installation

[rainman177]

is the dti guide mandatory or advisory/guidance. doesnt sound mandatory to me

 

[rainman177]

if the regs change ill change with them

GUIDE !!!! You takes the chance either he will pass it , you will be called back by customer because of nusiance tripping or will receive an NCR from the MCS inspector, which means you will have to alter it to pass inspection

your standard RCD is a type A (ignore the bit that says type B on your RCBO, thats refering to the MCB part of the RCBO) SOme inverters will prevent the correct operation of the RCD, so if one is needed it needs to be a type B for it to operate effectively.

This makes using an RCD a rather expensive business! It is generally considered rather bad form to use a shared RCD bevause of this, as it will be a type A but also because of other factors such as nuisence tripping and back feeding onto the installation, it's all very controversial and complex, so best just avoided!

most inverter manufacturers will also tell you in their instructions that you need a 100ma or even 300ma RCD so using a domestic 30ma is going against the manufacturers instructions, this is where nuisance tripping comes in.

as above better just to wire it so it doesn't need an RCD and avoid all the hassle!

P>S> yout titor was ill informed, out of date and ignorant it would appear not just of the requirements of solar, but basic wiring regs!

sadly, not unusual!

moggy are you suggesting i do not use an rcd at all, feels dangerous?

 

[jason121]

We have all been there, there is always something missing out the van when on site.

okay are you ready for this this is bonehead number two question although "i believe" it to be bad practice is it electrically sound and not breaking any regs to put the ac isolator on the SIDE wall inside of a kitchen cupboard where the cu is?

- - - Updated - - -

there is a wall on the other side of the side of the cupboard

 

[rainman177]

alright jason, thats proper confusing. how can you say one minute you need an rcd then you dont>????

 

[jason121]

Should be isolator near consumer unit for non skilled persons to isolate in case of emergency and one near inverter if in loft for maintenance
