UK 63amp-100amp

[Highlandbilly]

Have just bought a house but find main supply is only 63amp
Other houses in street seem higher going by street plan I take it the 35 in all other houses and 25 in mine is relevent to this but don't know what it means - picture is from Scottish and southern electric company

anyway 63 is not enough for todays power consumption
All tails seem to be for 100amp and just got smart meter put in this week
southern are sending quote but is it not their responsibility to get an adequate amp to my house
Also the wire coming is white and not the usual grey (better or worse i don't know)

You do not have any unusual or heavy loads. Your existing 63A will be heaps for your current needs.
nothing needs to be done unless you are thinking of adding something like a 10Kw electric shower. But I guess your existing (gas boiler?) delivers all your heat and hot water?

Have a shower but it does not seem to be on consumer unit unless its along with bath which is a Electric jacuzzi type
Heating is supplied by gas boiler but water from hot water tank

Only reason i am asking is that electrician that was in said it was low as most are 100amp and he says it will go first if any problem

P.s this site is so hard to navigate with all the adds but i guess there would be no site if no adds.

pps this is in cupboard along with the hot water tank is it just a punp

I think an inexperienced 'electrician' may have led you astray, here.

Persevere with the site. There are some very knowledgable people on here. I know it's barely usable on a mobile, but hopefully that will be sorted soon.

Yes, it's just a pump.

 

[telectrix]

Yes, it's just a pump.

it's not "just a pump". it's a nice shiny pump with green collars. and it has a thermal cut-out.

I have seen all electric installations on a 60A fuse, no problem.

New supplies round these parts standard are 80A single phase.

To give some more context to this, I have a property I look after that I designed/built about ten years out in the sticks that is also all electric. It has private bore hole, fresh and foul water treatment plant, 14kw's of ground source heating.... The AFTER diversity calcs are something like 220A if done to the book. It's been sitting on an 80A fuse coming from a 16kVA pole transformer for a decade, no issues.

Think you need to think again on this you could be on a looped supply and if so will require permission from the DNO for a Car charger point to be installed.
They may want to unloose you as well which could be at your cost.

Personally would keep quiet and just live with it

25 and 35mm sounds big for a supply cable to a house, we did a load of new bungalows 5 years ago and the DNO installed 10mm supply cables to all the cutouts...

I wired in a power quality analyser to my house for 2 weeks, for no reason other than to learn how to use it, and my peak current drawn was 17.5A (the meter was set to ignore brief spikes such as fridge compressor starting). The peak was when I ran the electric oven and kettle on together. Though my kettle draws only 4.9A. I have a 60A fuse in the cutout and during some extreme testing of electrical switchgear still didn't blow it.

100a is not the minimum for houses now, in fact in the majority of houses it is the maximum. Realistically 60a will probably be fine unless your going to stand in the shower for 3 hours while cooking a roast dinner and charging your car. It is possible to upgrade to 100a, but I highly doubt you'll ever need anywhere near that.

 

[ChrisElectrical88]

Just for reference I just clamped my tails while the lad was in the shower and we have got dinner cooking, lights on and TVs going... 46Amps. You will be alright ?

 

[Highlandbilly]

They got back to us quoting £134 to go from 63amp to 100amp seems cheap unless its Just a fuse change?
The cable going in is around half an inch across but has been painted so i cant make out writing see photo

 

[Taylortwocities]

For £134 it can only be a fuse change. That price is barely enough to cover the paperwork. Go for it, if it makes you feel better. Not needed though!
