My garage is not joined to the house, a metre wide path separates it.
At the moment power to the garage is via a 13 amp plug-in socket inside the house, with a short length of 16 amp flexible core which goes into a back box containing a choc bloc connector where it joins some 2.5 t&e that goes through the wall, under the path (inside a piece of gas pipe !!) and into the garage.
Originally it was just a spur off the single house ring main (1976 build) and done before I came here, including the use of gas pipe as a conduit. In fact even the main EDF incomer enters the house under the front door inside some yellow gas pipe, along the top of the slab next to the party wall and up into the wylex meter box. Only 4 inches of screed 'protected' this cable. Obviously done by a professional SEEboard electrician.
I have added the 13 amp plug so that the gge is now a 'portable appliance'.
If I proceed with the EDF car tarriff and their £299 charger what sort of cable would this require ?.
The CU is about 10 metres from the point where the charger could be fitted. Maybe 12 at most.
The cable would come through the void above the lounge ceiling through the cavity wall, down the outside of the house, under the path and up into the garage. I guess this would mean SWA but does that mean an additional box is needed next to the CU to terminate the SWA with a gland ?. Or do modern metal CU's accomodate a cable termination like this ?.
I might as well use this to provide garage power and light too but at some point someone will demolish the garage because that would allow space for a 2-story 12 metre by 2.5 metre side extension, so an economic solution might be better.
