Testing garage CU for assesment!!!

[swaley]

Blimey. Had to go to work guys sorry if not replied. Basically I've run a 6mm SWA from main DB to a 2 way garage DB. Didnt opt to use PME from house, instead earth staked the outside building. Obviously a big no no from the sparks on here. All I asked was advice about testing. Thanks

How does it connect at the house end.?
What is the configuration of the outhouse CU?

Into a 32a mcb - rcd protected board. 2way board in outhouse. Earth staked.

Hum .... so if the cabin trips the RCD it WILL affect the house.

Sounds like you have 2 x 30 mA RCD's in series.

32a mcb in main board.

What is the sub main connected to at the house?

32a mcb in main board.

What configuration CU do you have in the cabin?

Ahhhhh I was an apprentice at a site in Burnt Oak when on the 15th of February one of the sparks turned up.

He was asked how his Valentines date went with his missus and said not well as he had bought her some stockings and suspenders, she told him to F off and called him a perv and to wear them himself, which he did to work under his jeans and showed us all......... I was 18 he reminded me of Kenny Everett.......

They must of chaffed somewhat

Not necessarily not connected earth in main DB only in log cabin end. I agree now I should of created a main side in house DB and used PME for earthing, would of been a better solution.

On the basis you MUST have an RCD in the cabin ...

You clearly don't understand RCD's .......... they detect the imbalance of the line and neutral ......... the earthing is irrelevant.

You need to make "improvements" before your assessment IMHO

Hence creating a main side in main DB
