PAT testing on Construction Sites

PAT testing 110v equipment is very important as it reduces the chances of an accident on site. 

If you need 110v equipment PAT testing use the contact form to get in touch, or read on for more information. 

We provide testing of fixed and portable electrical appliances on building sites and for equipment to be used on sites; we will come to the site, your home, office, etc to do the testing.

Why do we use 110 volts on site rather than 230 volt?

If you are working on a formal building site than you are are going to need to use 110 volt equipment if operating off mains power; this is standard practice on UK sites and is often a pre-requisite for the insurance of the site.

The Health and Safety Executive advise that tools, plugs and cable designed for domestic use are not suitable for site conditions. They further advise that site workers should use cordless tools where possible, or those that operate from an 110v (CTE) centre-tapped transformer so that the maximum voltage does not exceed 55v.

110v site transformers are “centre tapped“; or dual phase. What this means is the 110 volts is actually reduced further to 55 volts x 2. This much lower voltage and current is much safer to use, and it is unlikely to cause you major harm if you accidentally touched a live wire.

How often should 110v tools be PAT tested?

Most sites will have onsite generators with 110v sockets attached to them for use by workers, however it is recommended that you have your own transformer, which should be PAT tested every 3 months whilst in use on site. Transformers convert the 240 volt current to 110 volt and then split that current into at least 2 outlets, to connect other tools; which should also be maintained to safety standards through user checks, formal visual inspections and 3-monthly PAT tests.

PAT testing 110v equipment is very important as it reduces the chances of an accident on site.

Of course 3-monthly is just a guide, and you may have done your own risk assessment that suggests a different frequency, which is fine too.

The best way to do the testing safely

For inspections of electrical equipment on building sites we recommend all equipment is brought to one convenient location, ideally outside the ‘hard hat’ area, so as to reduce the strain on the site insurance and reduce the risk of accident, but also as the best method to ensure all equipment is tested, and something in use on site isn’t missed.

We have experience working on sites, and full PPE, although our insurance doesn’t cover us to operate in hard hat areas, yours probably doesn’t either, so we find the safest method is for you to place all the equipment to be tested in the office areas, or canteen, stores etc where we can test them and do any repairs.

#Top Tip

When you’re using your power tool on site does it seem underpowered? Chances are you’re using a long extension cable. You need a shorter one – the further you are from the actual power source the more likely the power to your tool will reduce. To solve this problem you need to use a shorter lead, or get a battery operated alternative.

This is the sixth year of using DRA PAT testing Ltd. As in previous years, all the administration is smooth and it is easy to sort out a site visit. The pricing has remained very competitive and the service is great value for money. We intend to keep using the company for our annual PAT testing.
Another year, another excellent service. Thanks to the team at DRA we have had another very smooth and painless PAT visit. From the initial reminder, in plenty of time to get everyone at our end booked in and ready to bring mobile equipment to the office, to the friendly, polite and competent Tester, Jane, I can’t fault the service. We have been happy to refer this company on to others as they are very professional and reliable. Thanks to one and all. See you next year.
Super service from DRA PAT Testing yesterday.Jane is brilliant, knowledgeable and professional.Excellent company. We highly recommend.
