| CASE STUDY 1 - UPGRADE FROM OLD FUSEBOX | |
| Location: | A house to the west of Southampton, on the edge of the New Forest. |
| Job Description: |
Supply and fit new 17th edition consumer unit to replace existing fusebox. There are 2 freezers in the Garage, so the customer requested a non RCD protected circuit for the Garage. In order to comply with the 17th edition IEE Wiring Regulations, the supply to the Garage uses armoured cable rather than normal twin & earth cable. The 1st Circuit Breaker, to the right of the main switch supplies the Garage as per the customer's requirements. |
The new consumer unit installed to the customer's requirements and complying with the 17th edition Wiring Regulations.
The same consumer unit with service head (containing main fuse) shown.
Note the Earthing and Bonding (green / yellow) cables between service head and consumer unit.

| Location: | A house near Southampton. |
| Job Description: | Supply and fit a new 17th edition consumer unit, add main bonding to gas and water mains. Tidy up messy electrics around the fusebox. |

| CASE STUDY 3 - TWO LARGE FUSEBOXES | |
| Location: | A large old house near Hamble. |

| CASE STUDY 4 - UPGRADE FUSEBOX IN A TALL CUPBOARD | |
| Location: | A house in Chandlers Ford. |
| Job Description: | Upgrade a fusebox located in a tall cupboard by the back door to a modern consumer unit. This job was part of a total rewire detailed elsewhere on this website. |
The "Before" & "After" side by side for comparison.
| CASE STUDY 5 - UPGRADE A 1960s FUSEBOX UNDER THE STAIRS | |
| Location: | A house in Chandlers Ford. |
| Job Description: | Upgrade a fusebox located under the stairs to a modern consumer unit. The old fusebox contains asbestos parts. |
This type of fusebox needs to be dismantled in order to get to the fuses.
Having exposed yourself to that danger (live parts inside), the fuses contain asbestos.
The new consumer unit in place, complete with gas & water main bonding.
| CASE STUDY 6 - ADDITIONAL CONSUMER UNIT RATHER THAN A REPLACEMENT | |
| Location: | A house in Ashurst, near Southampton. |
| Job Description: | Supply and fit a new 17th edition consumer unit and Electrical circuits for power & lighting in a new kitchen extension. The existing fusebox is left in place for the circuits to the remainder of the house. Under the 17th edition IEE Wiring Regulations, Kitchens are treated as a "special location" and require RCD protection on all circuits including lighting. As the existing fusebox cannot be upgraded to fit an RCD or RCBO, the best option is to fit a small consumer unit for the kitchen circuits only. |
It's not always necessary to replace the existing fusebox. Here a small consumer unit was fitted for the new kitchen.
| CASE STUDY 7 - 1930s FUSEBOXES STILL IN USE | |
| Location: | A house in Hedge End, near Southampton. |
| Job Description: |
This house has been in the same family since it was built in 1938. Although the cabling has been upgraded over the years
from rubber insulated (which has a safe usable life of 30 years), the collection of fuseboxes were the originals from
1938 and in a very unsafe state. The incoming supply service head (the green box) is also
the original and known as a "coffin incomer" for a number of reasons, but mainly because
it's full of asbestos, is made of cast iron, and worst of all, has a tendency to explode when
disturbed as the internals have rotted away. The reason we were called was because there was a "funny smell of burning from under the stairs, and it might be the Electrics". |
A 1930's Fusebox in serious need of upgrade before it catches fire.
A new Consumer Unit with all the previous dangers removed.
The only thing left from the original setup is the electricity meter - that's what it took to make it safe!
