Meters and boards Question

[Luke105]

I work for a company who installs electric heaters.

Usually we remove old storage heaters and replace them with our heaters using the same point with a new switched fcu.

The fuse board is usually just an old Wylex type with just an on off switch and non switched fuses.
The board is powered from the live coming out of the radio teleswitch meter so to make the board live 24 hours we remove this cable and put it into a Henley block which has permanent live feed.

The questions are....
Are we allowed to touch these meters as there are stickers all over them saying property of the electricity board.

Secondly, using the old points coming from the old style board with just an on off switch. Is this ok?

As stated you cannot interfere with DNO equipment it is illegal so no you cannot mess with the equipment! Besides which it can potentially be very dangerous at that end of the installation and around the cut-out. As to the wylex rewireable fuse bridges they are fine in the sense you cannot say they must be upgraded, but I might recommend some upgrading such as RCD.

Should the board be upgraded or not.
I just want someone to answer the question.

It’s not an easy question to answer.
If the supply was not altered, then no the board would not necessarily need upgrading.
Problem is, you are converting two separate installations into one.
That could be classed as a new installation
In which case the whole new installation might need to be upgraded.

You might do better contacting the IET technical help line: 01438 765599.

The load is being changed. Not the supply.
Thanks.

I thought you said you were disconnecting the supply from one meter and swapping it to another.

So basically the meter has 2 live outs. One which is permanent and goes to the house board. The second live out is timed and goes to the storage heater board (only comes on eco7 times)

The eco live tail is taken out of the meter and put into the permanent live tail by use of a Henley block

Yes two customer connection points = two installations.

Well for me it’s like this. We are powering this board into the live tail via a Henley block.
The board is old with no rcd protection.
We are removing old heaters and installing new ones.
I just wanted to know the opinions on this.

I've yet to come across a customer who hasn't regretted making the switch to the heaters you describe.

What is the current rating of the new heaters compared to the old I assume that the fuses are all 16A and you are changing D.P switch to switched fused spur with 13A? therefore the load for that consumer unit is about the same but remember that you are installing additional load during the daytime now.
As a minimum are you doing an Earth Loop Impedance test at each point?

About the same id imagine

So, even more basically, you're bypassing the E7 unit, that having no output cable. As said previously, you're re feeding a CU.
Is a bit of swerving the regs going on, is your question, then.

Yes all marked as 15amp on the old wylex fuses.
13amp fused spur yes

What certification is being issued?
