TD28 waits for electric potential a series wait for electric potential link group terminal block fitting be used for ordinary industry with for civil use building electric installation, Prevent median contact shock with electric and prevent earth fault cause ¡¯s blast and fire ¡¯s wait for electric potential coupling, Building prevent thunder and electron information. Equipment prevents transient condition overvoltage and disturb.

Product will accord with GB50054 ¨D 95 GB/ T14821.1 ¨D 93 will be standard.

status, People touches N line also exist shock with electric dead possibility. Fors example certain electric apparatus¡¯s N line touch shell, This moment should electric apparatus still can normal work, So hards to discover N line touch shell. If should electric apparatus¡¯ outer shell with bathroom water pipe collide with, People baths in bathtub, Bathtub¡¯s drainpipe be in earth potential, Enter water pipe and N linear electric potential same, Both¡¯s difference of potential far be more than 2.5V, Even exceed 12V, This moment people sit at bathtub in touch enter water pipe, Then has life danger. Supposings that all metal body connection one body in a toilet, Then not exists difference of potential, Thus avoid shock with electric¡¯s maybe.
¡¡¡¡ Toilet¡¯s lamps and lanterns and electric heating showering wait for electric apparatus¡¯s metal enclosure. Already dependable contacts to earth¡¯s under situation, Does toilet otherwise want again do part wait for electric potential coupling? Still will do. Because electric apparatus metal enclosure though already and PE line do connect, And by PE line and conductive earth body connection, But with PE line joins with¡¯s metal enclosure¡¯s electric potential not certain is earth potential, Ases PE appear creepage current time in line, Especially is from contact to earth body compare far situation under at equipment, Because PE line exists resistance, This moment outer shell¡¯s electric potential maybe appear good enough to cause hurt¡¯s electric potential, So exists shock with electric¡¯s danger. Ases sanitary intercrop wait for electric potential connect behind, Even if equipment outer shell¡¯s electric potential far higher than earth potential, But because human body maybes touch go¡¯s metal object is in same electric potential. So people can not receive electric shock.
Adoption association conductive earth body, Do under general wait for electric potential copular situation, Does toilet otherwise want again do part wait for electric potential coupling? Still want. Because general wait for electric potential connection, Can not ensure all metal object be in same electric potential in toilet.
Part wait for electric potential link¡¯s way of doing at blueprint in is not draw¡¯s, Onlies use character express.

Concrete way of doing following:
¡¡¡¡ Will be all sorts of metal pipe in toilet, Structure(Includes¡¯s reinforcing bar in concrete floor) And comes into¡¯s sight in toilet, Uses not do be less than 4mm2¡¯s copper a core line, Passes wait for electric potential link group terminal block each other connects. Is like picture 3 Show. Waits for electric potential link lead or wall in darkness smear time want wear plastic pipe protection at floor, It aim is replacing lead convenience. Waits for electric potential link¡¯s metal pipe wait for metal body with wait for electric potential link in¡¯s terminator arrange between¡¯s resistance not should be more than 5 in range.¡¯s metal pipe¡¯s connect place ordinary not need plus step connection in toilet, If finding lead all badness time, Should do step meet. Ases¡¯s water pipe is plastic pipe or wrap model metal administer time in toilet, Waits for electric potential step connection can meet on tap water bibcock; Adopts metal water pipe time, Steps connection direct meet on water pipe.¡¯s sewage administer because with enter water pipe between is obstructed in toilet, So sewage administers also want do wait for electric potential coupling, Can meet on at floor drain¡¯s pipe.
