Ready-to-go Commercial SPD Boards
Mike Lawrence, Commercial MarÂket ManÂager – disÂcusses marÂket-leadÂing integrations of surge proÂtecÂtion device (SPD) within electrical distribution boards for commercial building applications.
ComÂmerÂcial SPD Boards
Mike Lawrence, Commercial MarÂket ManÂager, exÂplains how our new marÂket-leadÂing surge proÂtecÂtion device (SPD) boards for comÂmerÂcial inÂstallÂaÂtions are ofÂferÂing elecÂtrical conÂtractÂors a ‘ready-to-go’ inÂtegÂrated soluÂtion.
We now ofÂfers one part numÂber for every size of its TPN disÂtriÂbuÂtion boards with the inÂcomer and surge proÂtecÂtion kits factÂory fitÂted, savÂing conÂtractÂors time othÂerÂwise spent inÂstalling the inÂdiÂvidual eleÂments.
A comÂbinÂaÂtion of full surge proÂtecÂtion device inÂtegÂraÂtion within the MCB disÂtriÂbuÂtion board, and a numÂber of feaÂtures and beÂneÂfits to imÂprove surge proÂtecÂtion efÂfectÂiveÂness, means elecÂtriÂcians and end-users can be asÂsured that fitÂting our comÂmerÂcial SPD board guarÂanÂtees the very best surge proÂtecÂtion.
One of the conÂseÂquences of the 18th EdiÂtion of the WirÂing RegÂuÂlaÂtions has been an inÂcreased foÂcus on equipÂment proÂtecÂtion against surge tranÂsiÂent voltages. In comÂmerÂcial inÂstallÂaÂtions, the regÂuÂlaÂtions claÂriÂfied why and where a surge proÂtecÂtion device should be fitÂted, and outÂline that it is the reÂsponsÂibÂilÂity of the elecÂtrical deÂsigner to enÂsure the inÂstallÂaÂtion is comÂpliÂant.
The regÂuÂlaÂtions are clear. ProÂtecÂtion against tranÂsiÂent overÂvoltages needs to be provided where the conÂseÂquences caused by overÂvoltage could:
- ResÂult in serÂiÂous inÂjury, or loss of huÂman life, or
- ResÂult in inÂterÂrupÂtion of pubÂlic serÂvices and/​​or damÂage to culÂtural herÂitÂage, or
- ResÂult in inÂterÂrupÂtion of comÂmerÂcial or inÂdusÂtrial activÂity, or
- AfÂfect a large numÂber of co-locÂated inÂdiÂviduÂals
Such scenÂarios acÂcount for the maÂjorÂity of comÂmerÂcial inÂstallÂaÂtions, ranÂging from pubÂlic buildÂings and busiÂness premises, and reÂquire the inÂcluÂsion of surge proÂtecÂtion. In the unÂlikely event that a non-doÂmestic inÂstallÂaÂtion is not covered in the four scenÂarios above, then a risk asÂsessÂment needs to be perÂformed.
Should the outÂcome of the risk asÂsessÂment inÂdicÂate that surge proÂtecÂtion devices are needed, then it will be a regÂuÂlatÂory reÂquireÂment that they are inÂstalled. LikeÂwise, if the risk asÂsessÂment is not perÂformed, then surge proÂtecÂtion devices should be inÂstalled.
New from us – full integration of SPD kits within the distribution panel board
To supÂport elecÂtrical conÂtractÂors to reÂduce inÂstallÂaÂtion times, meet comÂpliÂance reÂsponsÂibÂilÂitÂies, and alÂleÂviÂate the need to purÂchase and fit sepÂarÂate proÂtecÂtion device items for boards, the inÂdustry can now beÂneÂfit from our factÂory fitÂted and fully inÂtegÂrated comÂmerÂcial SPD board to provide opÂtimum surge proÂtecÂtion perÂformÂance.
The new comÂmerÂcial boards have been enÂhanced to enÂable all surge proÂtecÂtion kits to fit within the disÂtriÂbuÂtion board – as opÂposed to beÂing locÂated in a sepÂarÂate enÂclosÂure. This inÂnovÂatÂive and marÂket-leadÂing soluÂtion provides the shortest conÂnecÂtions to the surge proÂtecÂtion device from the inÂcomÂing supÂply, and betÂter perÂformÂance when it comes to proÂtectÂing imÂportÂant and ofÂten valuÂable equipÂment.
No secondary upstream protection devices required
In the past, surge proÂtecÂtion devices reÂquired an MCB/​​MCCB or fuses in the disÂtriÂbuÂtion board to provide backup proÂtecÂtion usÂing one of the outÂgoÂing ways in the disÂtriÂbuÂtion board. Our new soluÂtion reÂmoves this reÂquireÂment. For exÂample, a four-way board reÂtains the abilÂity to be used for four TP ways rather than only three due to the SPD reÂquirÂing one dedÂicÂated way. ReÂmovÂing the reÂquireÂment for a secÂondÂary upÂstream device simÂpliÂfies and speeds up inÂstallÂaÂtion timesÂcales.
SPD kits for TPN boards
Our Type 1 SPDs have been tested to enÂsure they work efÂfectÂively in conÂjuncÂtion with a Type 2 SPD in a downÂstream TPN board. With the new regÂuÂlaÂtions adÂvisÂing that SPDs should be seÂlecÂted from a single manÂuÂfacÂturer to enÂsure they work toÂgether, we have gone furÂther with veriÂfied testÂing to enÂsure efÂfectÂive co-orÂdinÂaÂtion.
All Hager Surge Protection kits are CT2 type arrangements
To conÂform to SecÂtion 534 of the 18th EdiÂtion, our new surge proÂtecÂtion kits inÂcluded in the comÂmerÂcial SPD boards are CT2 type arÂrangeÂments. This means our SPD devices are apÂplicÂable for all comÂmon UK earthÂing arÂrangeÂments such as TNC-S (PME), TN and TT earthÂing sysÂtems and reÂmove the risk of inÂcorÂrect seÂlecÂtion.
We have also inÂtroÂduced solid copÂper earth links in all SPD kits, achievÂing a best in class up efÂfectÂive perÂformÂance measÂured at the main busÂbars of the disÂtriÂbuÂtion board.
To enÂsure opÂtimum surge proÂtecÂtion perÂformÂance and reÂliÂabÂilÂity so that equipÂment can be fully proÂtecÂted, our new soluÂtion ofÂfers factÂory fitÂted and full SPD device inÂtegÂraÂtion for ‘ready-to-go’ inÂstallÂaÂtions, the reÂmoval of the need for secÂondÂary proÂtectÂive devices, the use of shorter conÂductor paths, and the inÂcluÂsion of solid copÂper earth links.
It all adds up to a powerÂful, pracÂtical and efÂfectÂive surge proÂtecÂtion soluÂtion that will aid proÂfesÂsional conÂtractÂors and reÂasÂsure end-users alike.
