This will allow you to write the modifications, faults & repairs, what is there and who did what work on your electrical installation.
A history of periodic tests is included so that it is easily referenced. This Product is universal meaning it is suitable for single phase or three phase boards on any ac or dc voltage with up to 36 outputs. Supplied with a chain loop so that it can be hung on or next to the appropriate board.
You are advised to have one log book for each distribution board. Each book has enough space for around 40 modification records, plus separate repairs and test records, you can reasonably expect the books to last 10 to 20 years in the average premises.
