The Different Types of Domestic Consumer Units

The least complex type of shopper unit, the Main Switch board is provided with a 100A mains isolator as it were. At the point when the seventeenth Edition Regulations originally appeared many could not help thinking that the times of the fundamental switch load up, which is provided without RCDs, were numbered. Notwithstanding, Main Switch meld sheets, when utilized related to a full bank of RCBOs are currently being viewed as the absolute most ideal way to fulfill seventeenth Edition, as this takes into consideration complete partition of circuits subsequently forestalling disturbance stumbling. The drawback to this establishment is the expense as utilizing individual RCBOs is extensively more costly than utilizing RCDs with MCBs. Numerous property holders anyway will pay the additional expense for the true serenity that RCBOs give.

A ‘High Integrity Consumer Unit’ is one which considers prevalent division of circuits while as yet shielding all circuits from earth spillage. It does this by utilizing three nonpartisan bars which considers the utilization of 2 RCDs and an entire bank of RCBOs. The client may subsequently safeguard all ‘non-strategic circuits like lighting and ring fundamental on the RCDs while safeguarding all crucial circuits autonomously with RCBOs.

A split burden board, in like manner speech, is one which is provided with a Main Switch and RCD. Now that we work under seventeenth Edition guidelines the inferred stacking of a split burden unit is that MCBs ought to be placed on the RCD side while RCBOs are fitted on the principal switch side. A split burden board, utilized in this way satisfies the seventeenth Edition Regulations especially well and cost really as it safeguards all circuits against earth spillage while diminishing the gamble of disturbance stumbling on strategic circuits through great circuit detachment. The term ‘Carport buyer unit’ is applied to more modest purchaser units and there is nothing else especially unique about these customer units. Most ordinary homegrown conditions have modest number circuits in its carports, garden sheds and toilets and subsequently do not need the bigger 10 – 36 way combine sheets utilized in the fundamental family.

Carport units are regularly somewhere in the range of 2 and 5 different ways relying upon what is being utilized in the latrine. A typical shed with lighting and several attachments would utilize a 2 way unit while a studio utilizing a machine and power instruments could select a 5 way unit. These shopper units regularly accompany 2 RCDs and a full bank of MCBs and generally have somewhere in the range of 10 and 15 usable ways.
