When to use AFDD’s

[craigbanham]

We currently install industrial washing machines, driers and finishing equipment. These can be three phase and single phase. Normally no greater than 32 amps.

When on a commando socket we will install an AFDD.

If we remove the commando socket and install a standard rotary isolator, do we still need to install the AFDD ?

AFDDs are usually put in at the source, at the fuse board and would cover all circuits.

If AFDDs are specified, then it won’t matter if it’s an isolator, or a plug/socket… it should still be fitted.

Can you give us the make and model number of the AFDD you normally fit?
