Safety Switches (RCD testing) & Inspection
Residual Current Device (RCD) Testing or a Residual Current Circuit Breaker (RCCB) are more commonly known as safety switches mounted in your switchboard. These are designed to isolate power when an imbalance is detected between active and neutral conductors (a change of < 30 milliamps). These imbalances are commonly caused by current leakage through earth. The leakage itself can be caused by a faulty appliance or through the body of a person whom accidentally touches an energised piece of equipment. RCD/RCCB’s are designed to disconnect power to the circuit when a difference of 30 mA is detected. This disconnection, or tripping of the breaker, should occur without delay, if the RCD/RCCB takes too long to trip, the results could be fatal.
Installation of Over Voltage protection
Overvoltage protective devices are obligatory to protect your property from voltage fluctuations.

DIFFERENCE BETWEEN CAT5 - CAT7 CABLES:
CATEGORIES OF ETHERNET CABLE Ethernet cables are categorized into different categories. The mainly used categories are discussed in following table. The speed is measured in Megabits per second (Mbps) or Gigabits per seconds (Gbps) and frequency is measured in mega hertz (Mhz).
Ethernet cable category
Specifications
Description
CAT5 cable
Speed: 10 Mbps to 100 mbps
Frequency: 100 Mhz
CAT5 cable is the oldest and slowest UTP cable. Now these cables are not available in the stores, but are available with older router or any older networking device.
CAT5e cable
Speed: 10 Mbps to 1000 mbps
Frequency: 100 Mhz
CAT5e is enhanced CAT5 cable with additional increase in speed and reduced interference level. They support upto 1000 mbps or 1 Gbps of speed so they are often called ‘gigabit Ethernet’.
CAT6 cable
Speed: 10 Mbps to 10 Gbps
Frequency: 250 Mhz
CAT6 is successor of CAT5e with few more improvements in speed and frequency. The crosstalk (i.e. internal interference) is also reduced by making more twists in each copper pair. The new network infrastructures are using CAT6, so they are easily available in market. They require Gigabit compatible hardware for their installation.
CAT6a cable
Speed: 10 Mbps to 10 Gbps
Frequency: 500 Mhz
With reduced interference capabilities CAT6a allows connections up to longer range at speed of 10 Gbps. It has a plastic separator spine running in centre that decreases the interference.
CAT7 cableLength: 100m
Speed: 10 Mbps to 10 Gbps
Frequency: 500 MhzThese Ethernet wires are used for commercial purpose with maximum speed of 10 Gbps and need certified CAT7 infrastructure, failing to which will degrade their performance.
