E-ON just arrived to change our meter which has been running backward for 11 months and I have just been told by the guy who opened up for him that he looked at it and said that he couldnt change the meter as the "Neutral was wired directly in to the meter".
I thought all meters had both wires running into them ?
He said he he would have to liaise with the grid and come back.
*** Ahh - Thinking about it could he mean there is no board fuse for him to pull ?? ***
If we can get to August Bank HOliday we have had the meter running backwards for a year (26-8-10 install).

Is yours a old meter with a disc? If so, ask him if there is a separate import meter within, as somebody was told in another thread (see here ) |

I think the electric company is pulling the other poster's PL***ER !!
I did ask for a smart meter but they said they dont work with PV !!!

If there is no separate mains fuse for him to disconnect then he cannot safely isolate the incoming supply in order to replace the meter. Quite how you have ended up with a supply with no incoming fuse is another question.
I've only ever worked on live mains once in this sort of situation and I can say that it is exactly not the time you want your mobile phone to go off in your trouser pocket.

Surely there should never be a fuse in the neutral line since, if this blew in preference to the one on the live side, the power would be disrupted but the live would still be live - a potentially lethal situation. Maybe a link to act as a disconnect - but certainly not a fuse.
If there is no incomer fuse on the live side then I'd report this fact to the energy supplier since it is this fuse that protects the house from a major internal fault.
I'd suggest the guy was technically incompetent since the neutral is effectively at earth potential and he should be aware of that.

Looking at one of my 1st of the month pictures on my phone (makes reading it easie) i see the Live is fused but the Neutral is not. The wires come from a power pole in the street to the end of the building then inside the roof and down to the meter box - see picture.  All make sence now - they will have to shut down at the next fuse up the line i suppose and that feeds several houses !! |

Hi
I have only ever seen the live fused, never the neutral. As previously said the neutral should be at, or near earth potential.

I think they stopped fusing neutrals in the mid 50's.
If your installation has one report it and they will repair it.
Generally by fitting a new cutout or fitting a henley block in the place where the neutral fuse used to be located.

Ah, I misunderstood your first post then. I thought you meant you had no fuse at all. Now sounds like the meter-man fancied knocking off early. |

Maybe not, as there are the metering squads,the jointing squads and the cable install squads.
More than likely a jointing squad to install a new cutout or repair to make the neutral unfused.
Meterman will only be interested in fitting his quota of meters

ah, I think I understand. Usually the neutral coming in from the mains will terminate in the unfused section of the fuse block for the live side, then a set of tails will run to the meter. Looks like your's may have the incoming neutral terminating directly in the meter or something like that.

my first post don't be to hard on me X emeb / eon looking at the pic needs new overhead cut out before the meter can be changed In my day id have done the job if the customer wishes so !!!!!!!!!! Quotation from my manager before leaving emeb (we don't need experience we have computer's) looks like the disk will be going backwards for some time  |

Indeed, a fuse in the Neutral is a no-no.
If it blows all the wiring both line and neutral in the house would be charged to 240v which poses an increased electric shock risk.
Also if the line was not fused one could have a very large line to earth short circuit and with no local fuse the fault current could be very excessive and dangerous.

I worked in a house where the fuse was in the house next door, and there was only one fuse for both houses, and it was only 60 amp.   peas |
