Fuse in Power Lead plug

[Nagesh]

Are Kettle socket PDU strips disfavoured because the power leads going
into such strips do not have fuse in them?

What are the chances of something going wrong in a server so that if
the plug fuse does not blow up there can be bigger blow up in power
supply further away from server affecting other servers drawing power
from the same supply?

I am debating with someone who wants to use PowerLeads that have come
with the servers in 3pinPlug taking PDU strips by attaching additional
standard power cable to each cable that has been supplied with the
servers.

3pinPlug(male) houses its own fuse.

Thanks and regards

Depending on where you are and if the fuses in the leads are required, I'd
say "don't". The server is already fused internally, and the supply will be
fused. Just what are you protecting with a fuse in the lead? We run dozens
of servers and other critical pieces of equipment here and we remove any
such fuses from leads and power-boards as they are a potential failure point
with no benefit to us.

In a Datacenter like Redbus's Interhouse

Is anything to be gained by choosing more expensive PDUs like

OR
http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=AP9568

over cheaper ones like

?

Will be higly obliged for a response from experts like Mr Taylor.

The two rack-mounting strips look pretty much the same, and almost identical
to ones we use. They're convenient for mounting in the rack, as long as they
won't get in the way of the cabling. The first one you've linked to looks
like (hard to tell) one which we have a few of - it is like a 9-U panel
with outlets on it. It's more convenient if you have lots of cabling running
up and down the rack but most of the equipment in one area. You need to
decide how you're going to lay out your rack.

Note that these distribution units will almost certainly be fitted to
require a high-current source (approx. 15A at 240V for the ones shown). You
need to be careful not to overload your circuits. I'm not sure if these
British (?) units will have fuses in leads though, which IIRC was the
original question.

Not in all countries. And the power supply in that server was not
designed specifically for your country. It has an internal fuse.

Thank you very much, Ken.
