EICR Reports + Electrical Testing Reading

---

Initial verification is a process that ensures that an electrical installation is constructed and tested correctly and complies with the designers intentions. and a visual inspection is also carried out to ensure the installation is in good condition with no parts visibly damaged or defective

The R1 + R2 Test is to ensure that both the protective conductor and the live conductors are continuous throughout the circuit

Ring continuity is a test to ensure that any ring main circuits are wired correctly in a ring  

Polarity Testing ensures that all conductors are connected to the correct terminals and have not be crossed , reverse polarity could result in safety device failing to operate correctly during a fault , or cause damaged to equipment on 3 phase systems

 The insulation resistance test is an electrical test which uses a certain type and level of voltage (500V d.c. for low voltage installations i.e.: 230V) to measure insulation resistance in Ohm`s. The measured resistance indicates the condition of the insulation between two conductive parts. 

 An earth loop test is conducted in electrical circuits to evaluate the effectiveness of protective measures. It measures the resistance of the path that a fault current would take between the line and the protective earth123. The test ensures that the fault current is strong enough to set off the circuit protection, preventing overheating and fire1. 

The Residual Current Device, or RCD, is one of the most important electrical safety devices in both the home and commercial environments.

In short, an RCD protects against injury and death caused by electric shock by detecting an imbalance between the outgoing and incoming total current of a given number of circuits. 

RCd's Must be regularly tested to ensure their correct operation in the event of a fault

Functional testing is carried out on all switch gear and accessories such as isolators and switches to ensure everything is operation correctly to maintain safety and reliability . this is particularly important on older switch gear which may have been damaged or seized over time

electrical accessories are often get damaged over time and repeated use ! this can lead to exposed live terminals that could lead to a electric shock or loose connections that could result in a fire

 Rodents, such as mice and rats, are known for their tendency to gnaw on cables. Their sharp teeth can puncture insulation, expose conductors, and disrupt cable integrity. This damage can result in short circuits, signal loss, and even fires, posing a threat to both functionality and safety. 

Installations with a old fuse board will most likely have no RCD Protection

It is also common for Old RCD's to no longer operate within the required time 

Open Ring continuity Faults are very common, they are often caused by DIY enthusiasts , or kitchen fitters  because a cable has fallen out of a termination or because the circuit has not been wired correctly.  The are potentially very dangerous as there is a chance that the cable can be overloaded and potentially cause a fire . a Open ring circuit will not show any signs of a fault 

Poor connections often leave exposed live terminals increasing the risk of electric shocks and potential loose connections

  Loose connections give rise to heat. · This heat travels from its point of origin, along the conductor in both directions. · The insulation becomes brittle, delicate and disintegrates. · The result is a high resistance joint. · Possible damage to equipment. · Possible electric shock. · Possible fire hazard. 

It is a requirement of bs7671 for metallic services entering a property to bonding to the main earth terminal of the installation.

In older installations this may not  be installed or sometimes could be disconnected during building works
