New installations.

Are you thinking of or building a new home or business place (factory, office etc) in Thailand?
Are you concerned about the quality & correctness of the electrical installation?
Will your 'mains cable' be large enough in 5 to 10 years due to possible family/business expansion? Installing bigger 'mains' at a later date is expensive, time consuming & unnecessary. If things have been carefully planned, many problems can be avoided.

In all new installations, the first question is usually, "What size 'mains' do I need?"
This question can only be answered if Maximum Demand has been calculated. The Maximum Demand is also required for determining the size of a Distribution Transformer (in the case for businesses).

To calculate Maximum Demand, lots of information is required. For example;
1] the number of power outlets (double & single).
2] the number of light fittings as well as the type & size of the lamps.
3] cooking equipment (stoves, ovens etc).
4] air conditioning.
5] hot water heaters.
6] other extraneous equipment like pumps or motors etc.

The Maximum Demand calculation also assists in balancing the 'load' reasonably evenly across multiple phases (if you have a multi-phase supply) as well as establish the size & type of 'Consumer Unit' ('Main Switchboard' for businesses).

For the time being, I am freely available to assist anyone who requires help with this.
