Upgrading domestic supply (60A to 80 or 100A)

[SJD]

For SSE DNO area, if a customer was to request an upgrade of supply from 60A to 80A (or 100A), does anyone know if SSE normally make a charge for doing this?

Background: TN-S supply (Ze = 0.27 Ohm), late 1960's Bakelite-looking head which appears in good condition, mixture of 16 and 25mm2 tails, originally fed an old Wylex fuseboard rated at 60A, now feeds a new Wylex dual-RCD CU with 100A main switch. Property has an electric shower, electric oven, some electric heating, max demand is way over 60A.

If the supply cable is capable of 80 or 100A, it is maybe just a case of SSE changing the fuse?

If you say sse have the dno for that area, speak to them.Energy suppliers should not upgrade fuse's. Well we don't.

Some are up to 800A.

Very true, but highly unlikely to be found in a purely residential area. That sort of rating would only be found in subs feeding fair sized industrial estates or commercial shopping estates....

We're talking about fuses on the MV or LV side, here?
