), and how much protection is required for each circuit. High Integrity Consumer Unit - Usually used in larger properties with greater numbers of circuits, this type of consumer unit offers good circuit separation through the use of two or more RCDs whilst allowing for the independent use of RCBOs. The resistor passes more current than that required for tripping, and the duration of the test is not limited, so testing in this way does not provide proof that the unit is working to specification. Read carefully all the cautions and instructions and follow them strictly while doing this tutorial or any other work in practical related to electrical works. IEC & UK.

Some older systems such as those that use MK or old MEM Consumer Units that had one fuse per spur, so for instance: On this Wikipedia the language links are at the top of the page across from the article title. Ensure that busbar tangs/fingers are located correctly in the terminal (see Fig 13). In short, there should be two phase wires from the same line terminal of MCB. The output Live terminal of RCD should be bonded to other MCBs via a common copper busbar segment terminal. HAG VML110. The rail and the shape of the front opening are standardized but the busbar arrangements are not. RCDs have a test button which creates an earth leak with a resistor, and it is usually recommended that they are tested once a month. Another way to protect circuits under the 17th Edition IET Wiring Regulations is by fitting Residual Current Circuit Breaker With Overload (RCBOs) to every circuit, and although this is more costly than the RCD+MCB's option, it means any fault condition on a circuit trips only that circuit's RCBO, so the search for the fault is narrowed down from the start. Breaker Box Installation. < Consumer Unit Accessories Busbars A busbar is installed within a power distribution board and is designed to connect circuit devices to isolation devices. A garage consumer unit is used to feed up fewer load circuits (generally 2-5 units).

There were a number of similar designs from other manufacturers but the Wylex ones are by far the most commonly encountered and the only ones for which fuseholders/breakers are still commonly available. Although more expensive than a consumer unit with one or two RCDs and separate circuit breakers, RCBOs have the advantage that a fault will only affect a single circuit. The split board shown here has one RCD and is a simple version to show the user how the board works. The second condition applies to any circuits where an earth fault current is not sufficient to blow the fuse, or trip the switch, in the designated time allowance made in the regulations.

In this tutorial, we will be showing how to install a single phase garage consumer unit for 230V with RCDs according to IEC. It is because split load consumer units provide protection against overload, overcurrent & short-circuit and earth leakage. Ensure that busbar tangs/fingers are located correctly in the terminal (see Fig 13). Linking mcb in consumer unit with wire not busbar First of all, disconnect the Fuse between kWH energy meter and the utility pole to cut-off the main power supply. To connect a single phase 230V AC load circuit to the newly installed garage consumer unit, keep in mind that the Live should be taken from the output terminals of MCB and Neutral and Earth from the Neutral & Earth Busbar terminals in the CU respectively.
