Choosing Element Wire

[jmhbutler]

Quick questions:

When Kal suggests using 10/3 300V wire in his build, is there any harm in using the 600V equivalent if its more readily available?

I'm pretty sure its good but shouldn't be guessing when it comes to using 240V power.

Cheers,

No 600v is fine. I've used it in 2 builds.

Sure you can use it.
Moreover 300V rated wires don't fit requirements for 240V circuit wiring. Because "240V" its just an average (“Root-Mean-Squared” to be precise). But the peak voltage value is around 340 Volts

Fantastic,
Thanks for the reassurance and explanation.
