Possibly It all depends on your level of fault current and the protective device

Our step voltage is a little less than that of our four legged friends

Yes you should take into account the reactance of the armoring

For sale a brand new DGC 1000A

Its as easy as that? What about reactance of the armoring?

What the maximum ZS for a circuit supplied via a 300 mA RCD, any ideas Cheers

How do you calculate PEFC when using SWA, and using the armor as the CPC. Many thanksGuinness

Busbar temps are limited to those in BS 159 and BS EN 60439-1, 526.4 terminations to the busbar BS 159 and BS EN 60439-1, these standards give recommendations on how 526.4 is to be met

You seem to be getting confused between met and pen ian Think you best re read. Best re read again. Well they best re write the regs, GN5 , energy networks association recommendation G12/3

Im referring to rodding the at the met not the pen, as to which sidewinder is also referring.

I disagree completely, people are showing a lack of understanding

It all depends upon the pfc, if its high, you will require fused protection. I would agree with kme fused protection, unless 433.3.3 is applicable. Dont agree with using 433.3.1 as there is a risk of overload.

The only reg applicable that i can see would be 433.3.1, is it possible for a 24 way board to be overloaded? and it still needs to be protected against fault current reg 434

The problem would be on short circuit if you used a mcb you would have no short circuit discrimination, it would need to be fused.

You need to look at your protective device upstream of the db, now at a pfc of 16ka how fast will it disconnect, faster than the 10ms probably betwen 2 - 5 milliseconds, so no issues probably

I thought you two were supposed to be bez mates:^O

So im informed, product standards restrict voltages to 50v or less, so any test where for what ever reason will exceed the 50v the meter wont test ---------- Post Auto-Merged at 22:05 ---------- Previous post was made at 21:58 ---------- Dave on a TT where RCD protection is used for Fault...

In most instances dave you will rely on your rcd for your TT fault protection

No its fact steptoe, you might get away with it on old meters but not new, think it may go in new GN3

In some instances its advisable, placing a rod in a suitable impedance will reduce the touch voltage on a broken pen to that below 50v if designed correctly ---------- Post Auto-Merged at 12:22 ---------- Previous post was made at 12:19 ---------- I agree ads, 542 .1.8 has nothing to do with...
