现浇大模板住宅工程，该工程共8层，采用框架结构，建筑面积5285m2。该工程项目周围为已建工程，因施工场地狭小，现场道路按3m考虑并兼做消防车道，距离拟建房屋4m。搅拌机棚、砂石料只能在在建工程与已建工程之间的间隙堆放。施工供电设施已按照供电设计和施工总平面图布置完毕，并且建立了临时用电安全技术方案，方案内容包括：用电组织设计的全部资料；用电工程检查验收表；接地电阻、绝缘电阻和漏电保护器漏电动作参数测定记录表；定期检（复）查表。施工现场临时用电配置，以“三级配电、末级漏保”配电保护方式。 该项目在施工过程，发生如下几项事件：
事件一：在主体结构施工至第四层时，发现部分混凝土试块强度不合格，因此，施工单位聘请了有法定资质的检测单位进行现场实体检测，检测结果实体强度能够达到设计要求。
事件二：在外用电梯上升过程中，受七层阳台伸出的一根防护栏杆影响，架子工班长让正在脚手架上进行支模的木工王某立即拆除，王某随即进行拆除作业，结果不慎将钢管坠落，击中下方正在清理模板的张某，张某因安全帽被击穿，头部严重受伤，经抢救无效死亡。
该项目现场配电方式有哪些不妥之处，请指出并说明理由。
