Electric Pump Safety on Construction Sites

What voltage of is needed for an electric pump on a construction site?

110 Volt Pumps are always the Preference for Safety

Why? A lower voltage is safer and less likely to cause serious harm. The 110-volt supply is described as center-tapped to Earth and comprises minus 55-volt and plus 55-volt circuits, hence the 110-volt Potential difference, also known as the voltage - the IET Wiring Regulations 18th Edition refers to this as a ‘reduced low voltage’.

How do you get a 110 Volt Supply?

The most common way is to use a transformer from a 230-volt power supply, the transformers are normally bright yellow and have special socket arrangements so as not to be confused with a standard domestic 230-volt supply.

Larger steps? Sites may have central transformers or a generator for 110-volt supplies, again, the sockets are specific for 110-volt equipment.

Is 100 Volt a must for Portable Pumps?

Most professional sites will strictly insist that all single-phase portable pump equipment is 110-volt for safety and also insured. You must take effective precautions against the risk of death and injury from electricity during construction.

Damaged or Cut Pump Cable

As with any electrical equipment, treat it with care. Regularly inspect any equipment and take items out of service if they are damaged. Tools should be serviced by qualified personnel. Do not do makeshift repairs.

Don’t take the risk, isolate immediately
