never seen a 3.6 mt earth rod before?

hello,  been on a job today and they had a lighting test to done. it failed with a high readng… they have suggested installing at earth electrode 3.6mt. This needs to bring the reading down to below 10 ohms.  my Q is what does 3.6mt mean? as i have not heard of this before and can't seem to...

Also the new relay does not show 98,97,96,95 on the relay, they are just blank. The purple and red cable I have connected to nc. As it's not marked may they be the wrong way round? No that's what I said and my original thought. The wholesaler said the next one up is 32a. I can't see how they...

Yes 15a switching load. It was set at around 3a

What do you mean steps. Basically ask the wholesaler to do a like for like swap. But the only difference is the little switch at the bottom on the original one is max 15a but with 3a-8a. And the one i was given was 15a but 1a- 1.8a Both rated 415 v at 5.5kw

Thought so. Its a Overload relay with start and stop switch. But cuts out after 5 Seconds on 1a and then Cutts out about 32 seconds on 1.8a. Think they supplied the wrong relay

Hello. Just wondering what the switch is for on a relay? The one that rates from say 1a, 1.3a, 1.5a, 1.8a for example? Cheers

Each bored had rcd but the swa didn't

Yes incorrect polarity and it was tt

Black was n front end and then on the link boxes grey was n. Re did connections as the cores were cut to make room. So replaced the link boxes for larger ones Well after we did that no volt drop at all

They used 3 core. I found it by putting a amp meter around each core and got 45a on every core.

Just to let you know the fault was found and it was a simple mix up between n new coolers and old colours mixed up with the earth. Fault rectified

There is 240v with out the shower on. When the shower is on it drops to 160v. I can see the cable ran though the out side and loft. One one joint.

that is what i have done. its goes from the 25mm to the 16mm not 16mm front end then join on the 25mm. even if if it does drop cable size 16mm should still be ok for the total load.  front end 25mm swa 240v at 25mm to 16mm join 160V consumer unit. 16mm 160V

didnt say i couldnt find it just not found it at present, that why i asked you guys for a bit of help as i have not come accross this before. doesnt look like i will be coming back here i think i will go to another forum if the members in this place are like you! 

it was a joke jeeeesus 

not my only idea. but the one witch will make me the most money : )

main supply shows 240V with the shower on. testing the joint and  get 160V. the joint is around 25M along the 25mm. i am out of options other than to replace the 25mm with a full run. 

it was feed from a 3phase supply as the 3 phase supplied other units. they wanted the salon to be connected to the house supply as they have had PV installed and wanted the salon and house seprate from the other units.  looks like they have used the 16mm SWA from the orginal CU and joined it to...

as said the connections are sound. all looks ok. i was expecting to find it burnt out.
