The cable will typically be the first type if it contains a Type-A connector on one end, like in the picture above. The form of the connector that will fit into your device will be the second. Certain cables, such a USB Type-C to USB Type-C cable, are named for the connector that is present on both ends.
While most electric vehicles can handle 32 to 48 amps, the majority of Plug-in Hybrid Electric Vehicles (PHEVs) can only handle 16 to 32 amps. All else equal, the more amperage flowing into the vehicle, the faster the charge time. On the other hand, we advise against installing a charger that can handle more amps than your car can handle.

Three meters of silicone-bound, five-core, 2.5 mm heat-resistant cable (fit for 4.5 kW Saunarium, 3 kW, 4.5 kW OCSB, and Apollo 4.5 kW heaters)
The 6mm twin and earth cable's current carrying capacity is displayed in the table below. The 40A AMP home cooking and shower circuits are the primary applications for this cable.
According to Wikipedia, a 10mm cable has a current carrying capacity of 40–70 amps. For your 7kw load, amperage and voltage are negatively correlated. However, you should be good if 208 3phase.
9.5kW can be 39A or 41A, based on the voltage at which it is rated. Under ideal installation circumstances, a 6mm cable can handle 47A of current. Therefore, depending on how it is placed, 6mm might be used. It is customary to choose 10mm, though, as this would enable the installation of a higher rated shower at a later time.
10 mmInstall a 10mm cable if money permits; certain induction hobs call for it. You are therefore protected against anything.
You can utilize a 40/50 amp MCB when utilizing 10mm. The protection of the supply cable is the main purpose of the MCB. Only the necessary current will be requested by the appliance.
He installed a 10.5 kw shower using 6mm cable. Since then, I've spoken with two other electricians, and they both offer different opinions. One believes that 6mm is usually sufficient, while the other thinks that 10mm should be used instead. Using the voltage drop calculator suggested on this topic, I've found that I require 16mm.
