A garage consumer unit is used to feed up fewer load circuits (generally 2-5 units). First of all, disconnect the Fuse between kWH energy meter and the utility pole to cut-off the main power supply. Generally a "split load" arrangement is used with some circuits protected by the RCD, and others not. It is because split load consumer units provide protection against overload, overcurrent & short-circuit and earth leakage. 1x 63A 30mA RCD 2x Type B MCB (1 x 32A, 1 x 6A) Dimensions: 185 (H) x 127 (W) x 110 (D)mm BS 7671 IET Amendment 3 BS 61439-3 A consumer unit can use an RCD as the main switch. This rule pretty much covers every single socket in the house so the ring main should be placed on the RCD protected side of the consumer unit. As they must sense the current in both the line and neutral, they have connections for both. We Rely on Advertising to Help Fund Our Site and Provide Free Information.

Less common than the other types, an RCD incomer does not use a main switch. Staircase Wiring Circuit Diagram How to Control a Lamp from 2 Places? Moreover, having sockets and lights on alternate RCD's means that if a faulty kettle downstairs trips that RCD for example, the kitchen lights will still be available, avoiding the hazard of investigating the fault in darkness. If a fault develops on one circuit, all circuits would be switched off immediately. Ensure that all devices are engaged correctly on the DIN rail. This protects all areas including showers and cookers, but if one trips the other will ensure at least some lights and some sockets still work. 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 . In this case it is a 2.5mm cable for the ring main.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'diydoctor_org_uk-leader-4','ezslot_16',812,'0','0'])};__ez_fad_position('div-gpt-ad-diydoctor_org_uk-leader-4-0'); The live (O) is fixed into the top of an MCB on the RCD side of the unit, while the neutral (M) goes to the RCD neutral terminal block. If only a small amount of load points are needed to power up through mains supply, they install a garage consumer unit instead of larger consumer units especially in outbuildings. Wylex have no miss busbar connections and quick release technology built into their circuit. Ensure that busbar tangs/fingers are located correctly in the terminal (see Fig 13).

First of all, switch off the main switch or related MCB breaker in the main distribution board or consumer unit and make sure the main supply is turned off. 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. The older fuse wires are being replaced gradually by their modern equivalent, the MCB or miniature circuit breaker. Circuit-breaker on left-hand side incorrectly installed with busbar tang/ finger outside the termination clamp . This allows protection in full for all individual circuits and if one trips, all others will still work. We have used the followingIEC wiring color codes for 230V single phase supply voltage applicable in the UK and EU. The same wiring of split load consumer unit for RCD and RCBOs is shown in the following fig having the old UK wiring color codes (prior 2004). You may need more about the protection devices in the previous post under the title of differences between MCB, MCCB, ELCB & RCB, RCD or RCCB/RCBO Circuit Breakers. A smaller white lead is a functional earth connection. Outputs are via two terminals on the top of the device. It is also an offence to interfere with the seals on the electricity meter.
