The unit itself is over-priced and badly designed. The cable does not easily or securely wrap around the body for storage and the power plug does not have a holster to hold it – despite there being a plug like indentation in the middle. It has a secondary box whose sole purpose is to hold a 16A/32A selector switch. Why wasn’t this part of the main box design? We also had to have a BCD fuse box installed inline. Why wasn’t that in the main unit? Other domestic charge points have a fuse as part of the unit. The design is a bit of a lash up quite honestly! There are much better ones at lower price on the market. The installer was due to arrive in the morning. He thought he was coming in the afternoon. His morning job was cancelled and so he did actually turn up at our place in the morning anyway. He didn’t have the required fuse box, so disappeared saying he would be back first thing in next morning. He didn’t. We range the office and asked where he is. They said they would get back to me – they didn’t. It wasn’t until the middle of the following week that the installer turned up again. He blamed ‘the office’, the office didn’t know what he was doing and neither thought they should tell me what they were doing. A bit of a joke really! I have a second power point to have installed in another property. I will not be using chargemaster.
