At the survey the customer’s car has its charging inlet on the front corner, and they reverse onto the drive. What should the position of a tethered point take into account?

That the lead reaches the inlet however the car is parked

That it is as close to the meter as it can be fitted

That it sits at the back wall, where it is out of the way

Nothing, as drivers can buy an extension lead later on

A charge point data sheet gives IP54. Does that meet the Section 722 minimum for a unit on an outside wall?

Yes, it meets IP4X and IPX4 or better

No, outdoor units need IP65 or better

No, the first digit must be 6 outdoors

Yes, but only if it is under a canopy

An EV cable runs concealed 60 mm deep in a plastered block wall with no metallic parts. What does Table 52.1 require for impact protection?

No additional protection at that depth

A prescribed zone plus a 30 mA RCD

Earthed steel conduit along its length

SWA cable, whatever the depth is

Sample questions

01At the survey the customer’s car has its charging inlet on the front corner, and they reverse onto the drive. What should the position of a tethered point take into account?
- AThat it is as close to the meter as it can be fitted
- BThat the lead reaches the inlet however the car is parked
- CNothing, as drivers can buy an extension lead later on
- DThat it sits at the back wall, where it is out of the way
Why: The ENA guidance tells customers to think about the length of the cable and the location of the charge point so that it reaches the charging port, which can be at the front or the back of the car, and ADS 6.3 asks for locations that suit inlets in different places. 722.55.101.0.201.2 rules out portable socket-outlets, so an extension lead is not the answer.
02A charge point data sheet gives IP54. Does that meet the Section 722 minimum for a unit on an outside wall?
- AYes, it meets IP4X and IPX4 or better
- BYes, but only if it is under a canopy
- CNo, outdoor units need IP65 or better
- DNo, the first digit must be 6 outdoors
Why: 722.512.2.201 and .202 (A2:2022 wording; check your A4 copy) set at least IPX4 against water and IP4X against solid foreign bodies outdoors. IP54 is 5 for solids and 4 for water, so it meets both. IP65 goes beyond the requirement, and no canopy is needed. Keep the rating intact at cable entries (522.6.4).
03An EV cable runs concealed 60 mm deep in a plastered block wall with no metallic parts. What does Table 52.1 require for impact protection?
- ASWA cable, whatever the depth is
- BEarthed steel conduit along its length
- CNo additional protection at that depth
- DA prescribed zone plus a 30 mA RCD
Why: Table 52.1 (the A4 home for these wall rules, 522.6.202) says a cable 50 mm or more from the surface of a wall without metallic parts needs no additional impact protection. The prescribed zone with RCD, or 522.6.204, applies under 50 mm. With metallic parts, an RCD or 522.6.204 applies whatever the depth.

Common questions

Is the Physical installation mock exam free?

Yes, it is free with no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.

Can I retake the mock exam?

Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.

Does this count as a qualification?

No. This is independent practice material and does not award a qualification, card or certificate. Where a subject has a formal qualification or card, you gain it through an approved provider.
