Electricity pit not yet hooked up to main power supply

14 01 2012

In my last blog post, we said

In reality it took Jemena, the local electricity distributor, 26 working days to get the pit installed.

However, it seems that the electricity pit work has not completed.  Not only does the footpath need to fixed up properly with concrete, but the power line has has not been hooked up to the main supply on the pole opposite side of our street as evident by the power cable end hanging loose.  I wonder when will this be done?

We have an underground electricity pit

11 01 2012

We didn’t want an overhead power line to our house, so we got an underground electricity pit installed.  Most new houses built in an established area will have an electricity pit included in their contract (if one does not already exist).

We submitted the application for the underground pit on 9 November.  We received the quote to install the pit on 30 November and we paid it the same day.  The pit needs to be installed near a property boundary with the neighbours and we requested the pit to be installed on the side where the meter box would be installed to make connection up to the house easier.  Just prior to Christmas, the power pit location was marked out on the footpath.

And yesterday (11 January) we noticed that the underground electricity pit was installed when we visited the site.  When submitting the application for the pit, we were advised that it takes 20 working days from date of payment for the pit to be installed.  In reality it took Jemena, the local electricity distributor, 26 working days to get the pit installed.  Given the slowdown of work during Christmas holiday period, we think they installed it in a reasonable timeframe.  Overall it took 2 months from application to completed installation.

The power poles are on the opposite side on our street and the Jemena field officer who inspected the site determined it required 17 metres of cabling to complete the works.  The cost to install the underground supply, including the service pit and cable was $3392.

We went for 3 phase supply to cater for our future needs.  As technology becomes more interwoven into our lives, our power consumption will increase.  Furthermore, we are looking forward to turning our house into an icebox during the hot summer months so we will be installing a central ducted refrigerative cooling.  A normal 80A single phase supply will provide 19.2 kWe maximum.  So single phase supply could be overloaded when most things are operating (lights, fridge, tv, computer gear, central aircon unit etc) causing the fuse to blow.  This has happened to some friends of ours, especially during the summer months when the air con unit is running.

It is recommended to get the electricity pit installed prior to the builders starting work because 1) it will be cheaper to install 2) will save you money on building site costs as the builder doesn’t need a temporary power pole for the site works.  Here’s a blog post by another Metricon home build, Tim & Tina, about this.
