Thanks

More work on laying the cable next step ordering the charger

I have had a rolec for 9 months now and its been perfect.

6mm 3 core is what 3 Seperately sparkles all told me to use, I know it’s technically for 3 phase and whilst they may have all been lazy in maybe using the 3rd core as an earth rather than steel wire, they be the experts and they all said the same.

Fair enough, but if you are putting in an earth rod for a TT earth at the chargepoint (normal practice if house is on PME as most new build will be), then the 3rd core won't be connected to anything at all!

earth rod for a TT earth

not sure what TT means, but I remember when the podpoint electrician did the install he hammered a 3ft looking copper rod by the exterior side wall, took him 3 attempts as the rod kept hitting concrete foundations.

not sure what TT means

Sorry, it's jargon for one of the three earthing systems permitted in the UK public supply:

• TN-C-S (also known as PME) - "earth" wiring in the house is connected (before the meter) to the supply neutral, and that is connected to true earth (soil) with rods or grids at the transformer and down the street. Cable in the street is 3-core plus sheath, sheath being combined neutral and earth. Cable to a normal house is just 2 wires (or sheath and central core). Nowadays considered most suitable for most straightforward domestic installations.
  
• TN-S - Earth wiring in the house is connected to an earth terminal provided by the supplier, and a separate core in the supply cable connects to the earthed neutral point back at the transformer. Cable in the street is 4-core plus sheath, sheath being earth only and neutral having a separate core. Historically common in towns, now falling out of use.
  
• TT - Earth wiring in the house is connected to "true earth" with an earth rod or similar. Neutral at the transformer is also connected to true earth. No earth wire in the street at all - just 4 wires for the three phases and neutral. Historically common in rural areas with overhead wiring. Mandatory on farms, construction sites and similar "outdoor" locations.

These systems all have pros and cons, but where everything is indoors TN-C-S (PME) is normally considered the best compromise and so it's now almost universal in new installations for houses. Unfortunately, EV charging outdoors breaks that assumption and taking the TN-C-S earth from the house outdoors is considered higher risk than providing a separate earth on the "TT" system for the chargepoint.

This balance of risk is reflected in the wiring regulations; there are cases where the TN-C-S earth can be used for EV charging, but I don't think @Fellsteruk 's setup is one of them (assuming his house is indeed TN-C-S/PME).

I'm about to put an order on a rolec which is recommended considering I plan to be moving house in a year and a half? and thanks for posting the floor covers i will probably get some for me too.

Am I right in thinking a TWC will connect only to a Tesla? So say in a few years I change my Model 3 to something else, will I need a new wall charger? I'm not sure if the TWC has a propriety connector similar to Type 2 or it actually is a Type 2 that any other car could use.

 

[MrBadger]

TWC should work with any Type 2 equipped car.

I can confirm that the TWC works fine with the Kona electric. It is standard Type 2.

3.5 years using mine with zero issues!

As a bonus, I've been able to get the parts to change it from a tethered Type 1 (for my PHEV) to a Type 2 socket (for M3 and friends). Under £100 for the bits...
