## Questions & Answers

**Q: I plan to connect the generator output and the power company mains using this manual ts. where do i connect the 'earth' wire?**
A: The grounds are common, so the grounds can be connected together. The neutral needs to be switched through the switch.

**Q: can this take 16 mm cable in the terminals ?**
A: 16mm or 16 gauge?  It can take up to 14 gauge MAX.  I tried 12 gauge stranded and it wouldn't fit

**Q: How would i wire this to act as a spdt switch on 12v dc? i wish to switch between two power sources. any advice is appreciated.**
A: You would have to connect a jumper on the output side. (eg. sw to pos 1 will connect pole 1 and 3.  sw to pos 2 will connect pole 2 and 4. pwr source 1 to pole 1 and pwr source 2 to pole 2. add jumper btwn pole 3 and 4 and use pole 4 as an output.)  NOTE!! Check pole switching this is just an example!!!  also be aware of the amperage this is an AC switch box.

**Q: I need to switch between two ac sources, do i use 1/3/5/7 as the output? i follow that 2/6 for pos1 and 4/8 for pos2 , but what output terminals?**
A: Connect the load's hot wire to positions 1&3.
Connect the load's neutral wire to positions 5&7.
Connect AC Source #1's hot wire to 2.
Connect AC Source #1's neutral wire to 6.
Connect AC Source #2's hot wire to 4.
Connect AC Source #2's neutral wire to 8.

### ⭐⭐⭐⭐⭐ Deviatore elettrico di buona qualità
*by A***I on 18 November 2024*

Da un’azienda specializzata nella produzione di componenti elettrici, ecco un interruttore universale che può trovare largo impiego nell’uso domestico e nell’attività professionale. Si avvale di tre posizioni per deviare la linea elettrica verso più dispositivi utilizzando ben 8 terminali. Il contatto avviene in tutta sicurezza in quanto la manopola passa attraverso la posizione OFF che interrompe il passaggio di corrente elettrica. L’articolo arriva con la sua scatola di derivazione assieme a due guaine e alcune staffette metalliche. La protezione IP65 garantisce una certa protezione dalla polvere e dagli schizzi d’acqua, ma sconsiglio vivamente di posizionarlo sotto la pioggia diretta in quanto non è a tenuta stagna. La tensione nominale supportata è di 660 Volt a 20 Ampere, per cui possiamo tranquillamente gestire carichi industriali quali ad esempio motori per cisterne, martelli pneumatici, saldatrici e apparecchiature per uso professionale. Nel suo complesso, il deviatore fa il suo dovere e sembra mantenere stabile la posizione della manopola anche con l’uso intensivo. Le viti dei terminali sono di acciaio inossidabile e garantiscono una forte presa sui cavi evitando allentamenti e rischi di corto circuito. La possibilità di sfruttare fino a 8 terminali, consente di collegare più apparecchiature selezionando con un solo movimento quelle che devono accendersi o spegnersi. Oltre che in corrente alternata, il deviatore può lavorare in corrente continua permettendo di gestire dispositivi elettronici per uso domestico. Per la versatilità e l’ottimo rapporto qualità/prezzo, il mio giudizio sul prodotto è ampiamente positivo. Da consigliare.
