Filling out EIC tick sheet

[Rocboni]

Query when filling out EIC for an additional circuit,

When filling out an EIC for additional circuit, Is the tick sheet applicable to that circuit only or is is talking about the installation as a whole? For example where it states Cables correctly supported throughout their run obviously this would be a tick for the new install but it may be a LIM when talking about the existing circuits?

 

[Octopus]

The tick list is relevant to the incoming supply, earthing and bonding AND your new circuit.

"description of works" is what it covers

[Octopus]

Whether it be an EIC or a MWC, the "description" that you fill out, outlines what the certificate covers.

Simples.

Cover your a**s, I usually write some thing like "installation of new circuit supplying (whatever it is ) only, no other parts of installation tested or inspected.

Here's another one, when filling out a minor works for the addition of a panel heater spurred off a socket, socket supplied with rewirable fuse, RCD spur point then through the wall to and flex outlet, is the overcurrent device for the modified circuit the 1362 fuse or the rewiriable fuse?

Also Where bonding to water or gas/oil is not present must this be installed in order to complete the minor works?

 

[Ian1981]

If there's no protective bonding in place then installation works must not begin unless the services aren't extraneous in their own right or you plan to install the protective bonding when you carry out your works.

First thig I would check when looking at new jobs would be is the bonding in place, you have wired the spur off an existing circuit, the fuse or OCPD for that circuit should be noted on the Certificate

 

[Rocboni]

Ok so in this example the BS3036 would be entered on the MWC

Would a note be made that the existing circuit is not rcd protected?

If it needs to be RCD protected, that that upgrade should be done too - just because its a MWC doesn't mean you can avoid complying with the regs

 

[Rocboni]

So the rcd supplying the modified part of the circuit is not sufficient it needs to be at source? Who said anything about avoiding regs.

Should have been thought of at the outset of the work really Mate, same as the bonding, this heater is it in the bathroom?

 

[Rocboni]

Yes it's a panel heater, the rcd spur was installed next to socket and and heater supplied from this, but what you are saying the whole existing circuit must be brought up to current regs.

 

[Ian1981]

Only your work needs to be compliant with bs7671 so if your required works needs rcd protection then it's not necessarily a requirement to rcd protect the whole circuit you've spurred from , just your part.

The rcd protects the modified part of the circuit from the rcd spur point to the flex outlet in the bathroom, so this is correct?

Depends on how it was/is wired, are the cables buried less than 5mm from the surface of the wall

 

[Ian1981]

The rcd protects the modified part of the circuit from the rcd spur point to the flex outlet in the bathroom, so this is correct?

Yes but are the other circuits rcd protected in the bathroom or have supplementary bonding in place?

 

[Ian1981]

Only his installed cable need to meet that requirement not the existing circuit

 

[Rocboni]

What cables Pete, the existing or newly installed, the spur point is in the skirting board next to the existing socket wired as a 15Amp radial in twin and earth (big old farmhouse) basically goes straight through wall to the outlet.

Yes but are the other circuits rcd protected in the bathroom or have supplementary bonding in place?

No and no.

It seems like my tradesman should have highlighted these issues, I just want to know myself what's right and wrong.

Here's another one, when filling out a minor works for the addition of a panel heater (in a bathroom) spurred off a socket, socket supplied with rewirable fuse, RCD spur point then through the wall to and flex outlet, is the overcurrent device for the modified circuit the 1362 fuse or the rewiriable fuse?

Also Where bonding to water or gas/oil is not present must this be installed in order to complete the minor works?

Your work needs to be compliant so the heater circuit needs 30mA RCD protection as it is a bathroom, this is covered by the RCD spur.
The circuit from which you are working and the supply needs to be suitable for the load being applied and safe for continued use but not necessarily compliant with current regs assuming a 15A radial in 2.5/1.5 and a <2kW heater then it should be OK.
If the cable from the socket to the RCD spur is buried <50mm in the wall then that should also have 30mA RCD protection, but should be OK if the socket and spur are in contact.
The protective device for the certificate is the BS3036 15A, if the socket meets the disconnection time but the heater does not then the part of the circuit after the RCD spur can be protected safely by the BS1362 fuse, I would note this on the certificate if it were the case.
Earthing and bonding for the installation must be adequate for the protective measure applied i.e. ADS, therefore the main protective bonding for extraneous conductive parts should be in place and suitable.
You have increased the risk by installing an electrical item in a bathroom and there is some consideration that since there is not 30mA RCD protection to all the circuits in the bathroom that supplementary bonding for the bathroom (or 30mA RCD protection to all circuits in the bathroom) should be installed, but I would not usually do this unless the job were part of larger works.
