Jamieson Electrical Case Studies

Here is a taster of just some of the electrical services that Jamieson Electrical has provided to local industrial and commercial businesses since 1988.

Hampshire Cosmetics

Project - 1 x 630 amp sub main 140m from the main panel board to a central distribution position within the factory and to re-terminate three of the existing MCCB's on the panel board.

Challenge - To make way for the new 630 amp MCCB breaker in the main intake panel board that had no spare ways, install 3 x 95mm 4 core XLPE SWA cables and earth wire, above an office suspended ceiling, through a process hall then up to a height of 7m, running 70m then down to a MEM panel board. At the intake position to then terminate the 3 x 95mm's into a gland plate with no seemingly spare space.

Method - Intake position, take out a redundant supply contactor, link in the 630 amp MCCB with flexible busbar, re-terminate the 3 existing MCCB's. Cut large holes in the walls along the route, protect with carpet, install heavy duty cable tray. Pull in cables over a weekend. Dress cables onto the tray. Terminate the cables in the intake position by repositioning some existing circuits. Terminate the load end.

Result - The sub main was installed and the client was very satisfied with the work and how it was carried out.

The cable and our scissor lift are on route to the project, we actually hired in another two scissor lifts as a lot of the installation was at 7mReplacing the contactor and re-terminating the existing MCCB's with flexible busbar
Dressing in the three 95mm 4 core XLPE SWA cablesA bit tight for spare space on the gland plate, we use Piranha's on all our SWA cable glands, even the big ones
Finished 630 amp MCCB ready for the final switch on. Interesting point, other electrical contractors were approached but declined this project due to it's complexity
