Hi,

Just looking at having a switchboard retrofitted and asking any electricians out there if they have come across any Arc-fault circuit interrupter installs.

Reading up about them they look to be quite good for fire protection and mandatory in the USA. Are they used in place or in combination of RCD's

(note before anyone asks, most Electricians in NZ I've spoken too have not heard of these)

Thoughts?

If I understand the information in the Wiki article correctly the "combination AFCI" performs the job of circuit breaker, earth leakage CB as well as the arc fault interrupter. Since 2008 the "combination AFCI" has been the only accepted standard according to the Wiki article.

If the Wiki is correct then they do the job of an RCD.

Hi,

we have them on ships with HV switchboards. So you weren't allowed to take a flash photo in the main switchboard room lest you caused a blackout.

FYI, available in NZ with example code A9FD610. They're very new to our market.

We would have had them 8 years ago except the first batch of PDL ones burnt down a few houses in the USA...(I bet that hurt the wallet) ... So NZ decided to wait until the tech had improved a bit.
