I'm not worried about the power going off when testing as can reset it ok within a minute or so. It's just looking at the installation should there be any kind of electrical fault - even a fire this could cause the RCCB to trip and prevent access via the the gate so I'd tend to not want the Fire...
Opinions on this Crabtree TP 10 way board? Got to test this next week after a quick recce on a clients site yesterday. Although probably electrically safe the RCCB is feeding everything including another board Fed via an SWA and some external services also in armoured to. Thing that bothers me...
Hi,
I work for a company that is currently interested in recruiting an Electrician to be based from home and cover the M32/M4/M48/M49/M5 corridors and other motorway areas in the South of England. 17th/18th Edition with some Testing knowledge is desirable. PM if interested and 'll send you a...

I use Red or Orange Traffi gloves for General Testing and have a pair of Dewalt fingerless for domestic work when knocking out plaster/brickwork. Helps grip bolsters better.

RCD is a requirement too since it is highly likely to be used outdoors too 411.3.3
Where is that "Earth" attached to the Armour going?
Surely If the Earth and Neutral are reversed then the RCBO will trip immediately the power switches via the photocell as effectively only current flowing in the Line and Not back through the Neutral so there would be an imbalance straight away. Does anyone do a Cert? Recording R1+R2 values? I...
4mm Surely this will make the Grid busier by having thicker conductors, am I missing something obvious? I normally just use 2.5 bent into size to "pre-wire" it before putting the grid into position.?
Have you 16th or 17th edition already? I did a three day course with Trade skills for you in 2017 and all it was good for was to pass the exam. More of a refresh type course and explaining how to look and where to look to pass the exam rather than a real learning course as such.
